Lightning 500 kV 50 Hz

[TTimmyPokemonDude]

sounds like power chords XD

[Channellock12]

Ok here is my analagy. Picture one electron circling a neutron. I believe that is how it is feel free to correct it if I am wrong. Anyway if you could put a volt meter on the center of the neutron and the + probe on the ring of the circling electron would that not be the same as a voltage potential? If so then current is the amount of extra neutrons with electrons in a given area.

[KKinsane2009]

...I've actually been stumped about this for a long time, and my mate who worked with high voltage on ze railways tells me it IS the current that kills you, but, i'm thinking its the wattage that kills you. IE a decently high amount of current and volts. I say this because I do not for the life of me understand how you can get 100000 volts and not die but 0.2a kills you, or is it the frequency that kills you? O_o

and does that mean anti-electrons revive you (lol.?) seriously though im confused.

[gennaman2bit]

@KKinsane2009 U're right, it's wattage... or better... it's energy that kills u(wattage * exposition time), and yeah frequency is involved too.

In AC regime only 0.02A can kills u!!! In DC regime the deadly current is higher.

If u charge a capacitor to a very high voltage(your car is a capacitor and it charges moving on the road)and u touch it, the current is very high, but the discharge time is so quick that u feel just a little pain.

Touching a powerline for long time... that leads to death.

[67tr876]

@KKinsane2009 frequency can kill you too. You're hart beats 60 time's a min and 60hz can make you're hart want to beat 60 time's a sec there for killing you.

[Channellock12]

By the way Can anybody explain the differance between voltage and current? I have a good analogy to explain it but I would like to read others ideas also.

[martiallaw09]

@Channellock12 current=rate of flow of charge.

potential difference=electrical energy transformed per unit charge that passes between two points.

emf=opposite of PD in a cell, usually.

[gennaman2bit]

@Channellock12 think about a waterfall, the voltage is like the height of the waterfall, the current is like the volume rate of water flow.

Another hydrology example is a pipe circuit:

the voltage is like the difference of the pressures in 2 point of the pipe circuit, the current is the fluid flow: same pressure = no flow (voltage = 0 -> current = 0)

[Channellock12]

I can say this for sure. I had a small cut on my finger and I was working with 12 volt automotive. A small strand of wire poked into the small cut on my finger and I for sure felt current flow thru me but it was not high enough voltage to induce a large current. E / I X R no way around it. Try it if you don't believe me. A small razor cut to the finger changes your body resistance.

[thafff]

Sounds more like 60Hz than 50Hz

[redbear3100]

If I remember correctly from my construction electricity class in highschool (which was quite a few years ago) 0.1 amps can kill you. A nine Volt battery, with enough amps can kill you because it's not the voltage but the amps that kill you. But that's only if my memory serves me well...

[SmashCOBamberg]

u need at least 42 volts to kill somebody cuz otherwise the skin behaves as an insulater :-)

[redbear3100]

I'm not trying to be a smartass, but how the hell is your skin an insulator. The human body is like what 60% H2o? And if it was an insulator why do peoples finger tips and toes blow out when the electricity is searching for a ground? But all of this is futile really, because I mean come on, 500Kv? I know I wouldn't put my tongue on it...

[SmashCOBamberg]

i'm not talking about high voltages, i'm talking about low voltages with high amperage

[redbear3100]

Low voltage with high amperage. If there is current and no matter how low, it will pass through a conductor. I don't know enough to argue with you about it. But I just don't understand HOW our body, ever, can act as an insulator. I'll have to do some research now. If anything, thanks for sparking curiousity.

[Console880]

One Volt at an infinite amperage isn't going to pass through skin tissue. As mentioned above (depending on various factors, of course) you need around 40 or so volts for a current to pass through moderately dry skin.

[jtho53]

Console 880... go back to school. Its the amperage that frys you not the friggin voltage! 1 volt at 5KVA will fry you alive. Wanna be a geniea pig?

[Console880]

I'd kindly be willing to attach myself a power source as you mentioned. You need enough voltage to allow skin to be a conductor, instead of an isolator. No current with pass through your body at a low voltage you need enough pressure to break this barrier, basically. If your theory was true, wed all be dead from touching low-volt power supplies, 9V batteries, and low-voltage arc-welders. A car battery delivers around 12V at 400A youre perfectly fine touching the terminals of that.

[hajimari]

This is incorrect. It is current that kills you.

If you have infinite current, meaning current independent of any resistance present applied to a person, they would die. As little as 200-500mA can kill you.

[hajimari]

ur skin is an insulator. any insulator will break down and conduct if sufficient voltage is applied.

H2O is also an insulator or I should say a poor conductor. It's the salt present in any given amount of water that makes it conduct. When it comes to voltage, current and resistance they are all actively related to each other, since V=IR. With your example of 500KV and the impedance of skin being around 2k. You're looking at about 250A. The end points of your body blowing out, is kinda expected.

[NoIdeaHowToCallMe]

A 9V battery could kill you. But why would you connect it directly to your heart?

You can touch a welding transformer with 100amps @ 40volts and nothing happens.

The dry outer side of your skin is a good insulator. And you are wearing clothes.

You will need at least ~100V to break this insulation barrier. Naked.

Below 100V, your body has a resistance between 5000 and 100.000 ohms.

Read Ohm's law. The 9V battery can't send a deadly current through you, because the voltage isn't high enough.

[theringfilm1]

@NoIdeaHowToCallMe "what?"

[BGBejan]

However, our good old friend Ohm states that, if you got R you can't get amps unless you have enough volts.

[Console880]

Yes, exactly. You need sufficient voltage for a decent amount of current to flow through something with resistance. Ohm's law states this. In this case, the resistance is your skin. I have been shocked by a 45V AC power supply, though. Everyone's skin can have different levels of resistance, I assume. But, it's impossible for a power source of low voltage high current to electrocute you unless you bypass your skin completely.

[kambridge967]

sounds just like raidens electric on mortal kombat.

[fullrangechris]

Why the fuck does the current matter so much to people? Obviously it would either hurt like hell or kill you. lol

[ExtremeGamer55]

I had that happen in my backyard once, a massive storm wraped power lines around my tree then around the transformer, its was loud, blue, and vibrated the house as well, it was REALLY cool! The firemen wouldn't go near it, ComED shut the power down after we/they notified them, then the firemen went into action!

[knometo]

AFTER EFFECTS

[Inboundbogie]

You idiot ! ! HIGH VOLTAGE ! ! ! ! ! ! !

HIGH VOLTAGE very little Current

[TheBypasser]

Lol you are an idiot yourself for sure! The arc resistance depends on the loading characteristics of the supply, eg if the supply power is enough but the voltage is low you can still achieve a significant arc length if the breakdown has been initiated. Here the condition is set so that the supply voltage is enough to initiate the breakdown, but according to the arc look I guess the voltage drops well below 500kV while loaded, however the current is high.

[Inboundbogie]

Are you saying im the idiot here?? Are you an Electrical Technical Officer? or an Engineer?? come on ?

[TheBypasser]

Lmao you've just kicked yourself straight in the nuts! I'm a plasma physicist officially and also have some power electonics research as a hobby.

[jolo1691]

right! ;)

[BenHutchinson1]

Answer that guy's freak'n question! HOW MANY AMPS IS IT!

[WeeBiff2k7]

haha

[WDX7770243546]

How many amps is that?

[KironStrife]

doesn't need too many amps, just needs enough volts.

[WDX7770243546]

How many amps is that?

[WDX7770243546]

How many amps is that?

[rada1224]

around 1 or 6 AMPS

[HappyHippo4u]

its in Germany

[tall32guy]

It's obviously somewhere in Europe. I'm gathering in some type of substation or electrical facility? Looks like the sub. operators got bored and decided to play. :-)

[Cripwalker2006]

this is happenign in ur ass, when you drink coke and it meets, salt... BOYAAAAAKAA u stupid atomic101heli

[Atomic101Heli]

What?

[Atomic101Heli]

were the hell and what the hell is this??
