Tesla was all about AC so I think you might be thinking of Edison. AC is also hell of a lot better when it comes to motors which is one of the major applications. 3 phase squirrel cage motor is one of the best designs out there. Also dc is just as deadly: I'd hate to see what would happen if we had 120vdc in the household socket, lots of bad not let go electrical shocks. Sure dc is more efficient for transmission but generators output ac and most motors are ac so it's a more practi
anyone who doesnt know - voltage does not kill you. amperage does not kill you. FREQUENCY is what kills you. Take any lethal voltage / amperage combination - changing the frequency can make it non lethal. Humans die because 50 or 60 hz (cycles per second) does not agree with the human heart, and causes cardiac arrest.. anyone care to add anything? or correct any technical inaccuracies I may have stated? Im pretty confident this is 100% true in all instances.. correct me if Im wrong.
@LiquidChem it's almost completely wrong , it's the current that kills you , but current to flow on a conductor requires low resistance , or high voltage , that is why 1.5 volt isn't dangerous , if you still think that frequency kills , try reproducing 50 hz sound on yout computer and touch the output terminals from the green connector on audio card , you will be able to reply my comment ;D
@DjRaveKing are you fucking kidding me? AC absolutely causes the heart to palpitate at the 50 or 60hz cycle which is what causes fibrilation look it up jesus christ
@LiquidChem doctors can easy start your heart vith DC and stop it as well... defibrilator is just DC, stored in a capacitor. And this is ONE shoot. The same will happend if you touch DC hand to hand vith enaugh voltage.
I agree AC is more lethat ,but both WILL kill you in the right conditions.
i can give you mountains of evidence proving that DC is much safer and efficient than AC when used correctly. using AC current at 50 or 60 hz is not only retarded, its lethal and comepletely fucked. having it in homes is unnecessarily dangerous. it could easily be changed toa safer power supply.. i dont have time for you people anymore, do some research. learn the truth. tesla knows and tried to tell people just like you who wouldnt listen.
@LiquidChem Go and touch a 800KV HVDC line... And then you tell us others on youtube how i felt? Hello !!!! DC voltage or any alternating voltage for that mather with a voltage big enaugh to push a current of 5-10mA through your body should be avoied at any time.
Ps. don't touch the HVDC line, it will vapourize you. Remember what power can do. I X I X R=P
@LiquidChem Anything over 43 volts, ac or dc, can be lethal, because the amperage needs a voltage to overcome the resistance of the body. It dosent matter of the frq.
@nakayle i guess this is all incorrect then, you should edit this wiki page bro and the thousands of other web pages containing the same information.: high voltage frequency: wiki pedia . org/wiki/High_voltage
@LiquidChem wow, you sure are retarded, 100volt,1amp can fry your brain quite good. 5volt 1K Amp AC can only make you giggle the finger tips. its all a matter of Higher voltage (to make the power flow thru a body) and a little bit of amp (.50amp can kill someone).
I have a question. More like 3 of them. :) Can you touch just one pole (the one connected to the source) and not be killed ? And also what about voltage, if I have 50KV and 1mA is that the same concept like here in the video ? I saw a tesla experiment when he melt down a metal rod and touched both poles himselfe and was not killed. Is that the high current or high voltage scenario ? Much appreciated thnx :)
@kurentmalik You mean touch one side of the AC line? While in theory if you are not grounded, no you wouldn't get a shock. (this is how isolation transformers do their job or protecting someone against electrocution). However I wouldn't risk it. 50kV at 1mA would certainly give quite a kick, but the current there is not sufficient to cause any lasting damage. Melting down a metal rod & being able to touch both poles is most definitely high current/low voltage.
I've been thinking about high currents recently for electrochemistry, e.g. plating / electrolysis.
One easy source of them is computer power supplies. The newer ones can do massive currents in almost no space. You can also score arm fulls of them for free or 99p as people dump their old ones. If they were run in parallel direct from the meter tails, that's a very large amount of current.
Hey YOU THERE!! wurd ya getts that there rock bar ? Kinda lookie's likes the one use to rest in my geerauge,grewed it some leggs and took off,,missing that bar wanna gitts hur back someday
@Driv3th3hiv3 . This is the best answer so far !! It's true,but the resistance in this case was so low i got full power. (I did the same test with poweranalycer on the input) If i connect to it's full length, the current is decreased significantly. And thats why i can't connect to the heavy duty cables 240mm2 . I tryed with 1,5" copper pipe and it glow very nice aswell !
Hmm well i did step it down to 24 volts, then up to 240 volts, then to around 7000 volts the second time i tried it, but my second transformer ( 24 to 240 ) got really really hot and stopped working, so i had to fix it.
and you arent getting killed because....why? im an engineer major in school. i dont understand why you wouldnt be completing the path and the resistance of the human body (100~ohms) turning you into a chicken crisp?
either answer my question and backup what you have to say with electrical, logical reasoning instead of beating around the bush simply saying the obvious since the video is right above your head, or shut the fuck up trying to argue over a inobscure point like a 4 year old.
i never said it wouldnt matter, corrected myself, and your ass still hasnt answered my question 5 days later. fuck off dude.
Calm the fuck down you little child, and stop acting like being tuff on the internet is cool. You are the stereotype of the typical 12 year old youtuber who knows EVERYTHING.
1.58V is not enough tension to drive a lethal current through your body. The resistance is just too high. You won't actually feel a thing even if you touch both poles of a car battery, because 12V still isn't enough to push any significant current through your body. Take a multimeter and measure the resistance between your hands. Then take a calculator and calculate the current by using ohm's law. Tension / resistance = current.
Additionally, the guy in this video is not completing the circuit with his body, he is completing it with the steel rod. The two copper bus bars are the outputs, and he shorts them out with the rod and not his body.
@bonecrime Are you sure? As far as I know a human body in normal condition has a resistance of 10kOhm. When you're skin is wet, the resistance will drop. Correct me if I'm wrong, but 120kOhm sounds a bit too much
Assuming both voltages are RMS, let's say 40V AC RMS. Some higher frequencies are safer on the body to a certain degree (Skin effect is introduced) but in opposition eventually nerves will not respond to a frequency which is too high. Depends on the wave type and duty cycle though.
@TheToastPeople | Yeah man he shouldn't have any problem. Voltage isn't a problem but difference of voltage is. This means that if he held it with both of his hands we would see something like this 2:00 . But after 2 seconds his hands would sublimate.
men voltage doesnt kill people, is the current that could kill............. you could be at 800 kV in reference with ground, and be safe if you are "far" and no connect directly with ground trought wire.........
if you are near could leap an arc.....or if you are connect by a wire you should say good by to this world
Voltage alone doesn't kill people, neither does current alone. In order to be harmed or killed, you need both current and voltage. It is claimed that more than 0.5amp will stop a heart, which is true, but you need the voltage. Human skin isn't very conductive, you need at least 60-80volts to penetrate skin. Hence you can touch both terminals of a car battery (12v) and not be harmed, even though a car battery can give out over 300amps!

Why the ROD is heating from one side. In my CAR, there's a problen of fuse melting. The Fuses only melts from the one side and not on the other. They are plastic based. Similarly, I have a split AC install into my room, the switch maybe was not of high AMP, the connector got metled along with the PLUG. Only one PIN melted. I have seen this similarlity in many places, but never had really understand it. Does that means the melting point is HOT side. But why in Car, it has a 12V battery 50AH?
In your cases, only one side most likely heats up due to a bad connection. A bad connection = resistance, and a resistance with a current through it equals heat. The reason the rod heats up from the end first is because of thermodynamics, the heat is beeing spread out to the rest of the rod. And that makes it heat up at the tip first.
Shortly before the old wankdorf was torn down there was a test of the power supply for its lightfield. At the end they used a crowbar too (signed by some of the players). 110kv at approx. 2.2kA stepped down to 10kV at 20kA to prevent arching. Two about 30cm diameter copper terminals with the crowbar falling down from 2 meters. It just disappeared in a cloud of sparks. The video is part of an arte docu about electricity. It also shows that famous russian transformer explosion in full length.
Having read some comments, I could not resist a comment myself, to clarify that that is a nice transformer!
That is 5000 amps easy, if it had about 750 volts to go with that 5000 amps it would chew that bar up very nicely in seconds and spit molten steel everyehere, oh and shopping trollys vapourise nicely too, some will get it others will not :)
Voltage makes the arcs. Current heats stuff up. Of course, high voltage stuff can be very hot too, but lower voltages are easier to produce at high current (of course, steel plants use high voltage AND current - like 50,000 amps!) He didn't get shocked because the current took the path of least resistance - through the metal and back into the transformer's secondary. It's like when you pull a button in a DC circuit to ground with a resistor.
well if you were smart nwfklan you would know that if you had any amp through your heart all you would have to do is touch the other electrode if it was ac current he would fry. it has nothing to do with ohms
The steel bar doesn't get red-hot, it gets PINK-hot! That is so cool, and it's to do with science. I suppose different metal may vary in "hot" colour.
5000 amps would blow that steel rod to nothing. Furthermore, assuming you were using the 120vac power line, and that your transformer drew, say, 10 amps, you would have an efficiency rating of 700%, which is simply impossible. Even if the transformer drew 20 amps, it would still be well over 100%. Please re-check your numbers.
No, no,no... Be sure before you write something like this. 21Amps@ 400volt is a lot of power (8,4kVA).But In no way this amount of power would blow this rod to "nothing". To do this we need to be in the range of MVA .
It's impossible to explain for a person that simply don't understand. I will not follow this, trying make you understand . actually it's a waste of time. END OF STORY.
Ohm's law dictates the properties of resistance. Henry's law, on the other hand, dictates the properties of INDUCTANCE. If you are going to call me out on somthing, make sure you know what you are talking about.
im sorry but thie guy needs to get out more, if he knew anything he'd know that holding a metal bar as he is next to the transformer will induce a current in the pole as a magnet does in a piece of wire, it's first grade physics
so... what the point? And a quarter turn would be lethal? approximately 0,395volts end to end. An the current iduced is VERY low. You really think a mettal housing where you install a transformer is full of current? Your amplifier, cd-player microwave owen,welder..... I's minimal. Thank's.
The impressive thing is that while the metal rod is being heated at it's edge, you can hold it with a naked hand. Why the heat did not transfer through the metal rod?
you only forgot the part that you only need 40 mA through your heart to kill you instantly. so next time you go playing with high current transformers, just dont touch the rod, unless you like your heart to skip a beat
like a welder, the energy travels from pole to pole. If you get between the poles, then you get a shock. I want to know where the sound comes from. Transformers have no "moving" parts, so whats making the sound? Are the coils vibrating? That is about 60 cycles isnt it?
It depends of the voltage. I promise you are completly safe up to 24v (if you not put your tongue on the poles or do anything else stupid) and this is regardles of the output current. With the higer voltage it start to "push" to much current trought your body. What i think is dangerous is that you handle with deadly voltage on the primary side of the x-former. To do this without the knowlage of electricity can be the last thing you do !!!!!
Sorry, I guess Resistance between two fingers is measured (when sweaty) at 10K Ohms - 15K Ohms, and when dry apparently it's upwards of 1M Ohms. (DISCLAIM: DO NOT TRY THIS EVER, I AM NOT VERY GOOD AT PHYSICS, PLEASE CONFIRM CALCULATIONS FOR YOURSELF.)
so as low as 20 mA can kill (0.02A), but then you need to factor in Skin resistance and Voltages (which when low don't allow much current to flow).
"The amount of current through a body is equal to the amount of voltage applied between two points on that body, divided by the electrical resistance. The more voltage available to cause electrons to flow, the easier they will flow through any given amount of resistance. Hence, the danger of high voltage is potential for large amounts of current through your body"
so... this is plugged into a wall socket or something?

Well the reason it did that is clear.
The primary (High voltage side has a high resistance) abd the secondary (12VAC) output has very low resistance
When you connected the secondary to the mains the current draw would've been huge, because of the low resistance. thus flicking the breaker
Driv3th3hiv3 1 year ago
The best way to do this would to use the 12VAC output to power a different transformers secondary, and you should get 120VAC from 12VAC.

either answer my question and backup what you have to say with electrical, logical reasoning instead of beating around the bush simply saying the obvious since the video is right above your head, or shut the fuck up trying to argue over a inobscure point like a 4 year old.
i never said it wouldnt matter, corrected myself, and your ass still hasnt answered my question 5 days later. fuck off dude.

1.58V is not enough tension to drive a lethal current through your body. The resistance is just too high. You won't actually feel a thing even if you touch both poles of a car battery, because 12V still isn't enough to push any significant current through your body. Take a multimeter and measure the resistance between your hands. Then take a calculator and calculate the current by using ohm's law. Tension / resistance = current.

I just measured myself and got a resistance of about 120kohm between my hands with wet fingers. And this transformer puts out 1.58V. Thus:
1.58 / 120000 = 0.000013A
Wich is not anywhere near lethal ...
A 12V source would be able to push 0.0001A. Still nowhere near dangerous.

Additionally, the guy in this video is not completing the circuit with his body, he is completing it with the steel rod. The two copper bus bars are the outputs, and he shorts them out with the rod and not his body.

@bonecrime Are you sure? As far as I know a human body in normal condition has a resistance of 10kOhm. When you're skin is wet, the resistance will drop. Correct me if I'm wrong, but 120kOhm sounds a bit too much

partially true, however bringing AC current into the equation makes resistance slightly more complicated.
40v AC will easily shock you and drive enough current through you to kill. Depends entirely on not only voltage and current. But Frequency.
devosbi 1 year ago
@devosbi Well, yes, the peak voltage of AC is higher. 40V AC would actually be somewhere around 56V at the peaks, and that can be dangerous.
How the body reacts to frequencies, I don't know. Never read anything about it.
bonecrime 1 year ago
Assuming both voltages are RMS, let's say 40V AC RMS. Some higher frequencies are safer on the body to a certain degree (Skin effect is introduced) but in opposition eventually nerves will not respond to a frequency which is too high. Depends on the wave type and duty cycle though.

men voltage doesnt kill people, is the current that could kill............. you could be at 800 kV in reference with ground, and be safe if you are "far" and no connect directly with ground trought wire.........
if you are near could leap an arc.....or if you are connect by a wire you should say good by to this world

@metantonio
Your kind of right.
Voltage alone doesn't kill people, neither does current alone. In order to be harmed or killed, you need both current and voltage. It is claimed that more than 0.5amp will stop a heart, which is true, but you need the voltage. Human skin isn't very conductive, you need at least 60-80volts to penetrate skin. Hence you can touch both terminals of a car battery (12v) and not be harmed, even though a car battery can give out over 300amps!

Why the ROD is heating from one side. In my CAR, there's a problen of fuse melting. The Fuses only melts from the one side and not on the other. They are plastic based. Similarly, I have a split AC install into my room, the switch maybe was not of high AMP, the connector got metled along with the PLUG. Only one PIN melted. I have seen this similarlity in many places, but never had really understand it. Does that means the melting point is HOT side. But why in Car, it has a 12V battery 50AH?
umery2k75 2 years ago
In your cases, only one side most likely heats up due to a bad connection. A bad connection = resistance, and a resistance with a current through it equals heat. The reason the rod heats up from the end first is because of thermodynamics, the heat is beeing spread out to the rest of the rod. And that makes it heat up at the tip first.

the primary could high voltage but the secondary will not be looking at the size of it it would only be a few volts but large amperage
billmcg980 2 years ago
Shortly before the old wankdorf was torn down there was a test of the power supply for its lightfield. At the end they used a crowbar too (signed by some of the players). 110kv at approx. 2.2kA stepped down to 10kV at 20kA to prevent arching. Two about 30cm diameter copper terminals with the crowbar falling down from 2 meters. It just disappeared in a cloud of sparks. The video is part of an arte docu about electricity. It also shows that famous russian transformer explosion in full length.

Having read some comments, I could not resist a comment myself, to clarify that that is a nice transformer!
That is 5000 amps easy, if it had about 750 volts to go with that 5000 amps it would chew that bar up very nicely in seconds and spit molten steel everyehere, oh and shopping trollys vapourise nicely too, some will get it others will not :)

hang on a min, if it is huge current, then why isn't making big noisy arcs like in a jacob's ladder? and how didn't he get shocked?
a380rockerfan 2 years ago
Voltage makes the arcs. Current heats stuff up. Of course, high voltage stuff can be very hot too, but lower voltages are easier to produce at high current (of course, steel plants use high voltage AND current - like 50,000 amps!) He didn't get shocked because the current took the path of least resistance - through the metal and back into the transformer's secondary. It's like when you pull a button in a DC circuit to ground with a resistor.

5000 amps would blow that steel rod to nothing. Furthermore, assuming you were using the 120vac power line, and that your transformer drew, say, 10 amps, you would have an efficiency rating of 700%, which is simply impossible. Even if the transformer drew 20 amps, it would still be well over 100%. Please re-check your numbers.

No, no,no... Be sure before you write something like this. 21Amps@ 400volt is a lot of power (8,4kVA).But In no way this amount of power would blow this rod to "nothing". To do this we need to be in the range of MVA .

so... what the point? And a quarter turn would be lethal? approximately 0,395volts end to end. An the current iduced is VERY low. You really think a mettal housing where you install a transformer is full of current? Your amplifier, cd-player microwave owen,welder..... I's minimal. Thank's.

The impressive thing is that while the metal rod is being heated at it's edge, you can hold it with a naked hand. Why the heat did not transfer through the metal rod?
hrbear 2 years ago
you only forgot the part that you only need 40 mA through your heart to kill you instantly. so next time you go playing with high current transformers, just dont touch the rod, unless you like your heart to skip a beat

There's no way you'd ever get 40mA through your body from the secondary of that, though. It's simple to work out why.

wahtonka33 2 years ago
like a welder, the energy travels from pole to pole. If you get between the poles, then you get a shock. I want to know where the sound comes from. Transformers have no "moving" parts, so whats making the sound? Are the coils vibrating? That is about 60 cycles isnt it?

The iron core of the transformer is moving because of the changing magnestic feild around it and that makes a nois

Someone please tell me, is it dangerous to use a High current transformer? lol
Or are the voltages just too low to allow a lethal dose (0.02A) to enter the body?
tolsonw 2 years ago
It depends of the voltage. I promise you are completly safe up to 24v (if you not put your tongue on the poles or do anything else stupid) and this is regardles of the output current. With the higer voltage it start to "push" to much current trought your body. What i think is dangerous is that you handle with deadly voltage on the primary side of the x-former. To do this without the knowlage of electricity can be the last thing you do !!!!!
fragglan 2 years ago
Sorry, I guess Resistance between two fingers is measured (when sweaty) at 10K Ohms - 15K Ohms, and when dry apparently it's upwards of 1M Ohms. (DISCLAIM: DO NOT TRY THIS EVER, I AM NOT VERY GOOD AT PHYSICS, PLEASE CONFIRM CALCULATIONS FOR YOURSELF.)
so as low as 20 mA can kill (0.02A), but then you need to factor in Skin resistance and Voltages (which when low don't allow much current to flow).
tolsonw 2 years ago
"The amount of current through a body is equal to the amount of voltage applied between two points on that body, divided by the electrical resistance. The more voltage available to cause electrons to flow, the easier they will flow through any given amount of resistance. Hence, the danger of high voltage is potential for large amounts of current through your body"
so...
V / R = I (that would flow through the body?)
in this case:
1.58V / 1000Ohms = 0.001A (or 1mA?)
which wouldn't be fatal?
tolsonw 2 years ago
@tolsonw the resistance of the skin is way
