All about capacitors

[bozsikandor]

nice video :)

[verymetal86]

I now understand ! Bloody Great vid man !!!! Nice One !!!!!!

[prence1725]

are you a teacher? you explain it %100 correct

[oxide112]

Is it safe 2 discharge high voltage caps that way ? with a knife?

i always been tought 2 use a Resistor but this would be easier... but than again i work with high voltages 110/400/600V ( Tube amps in case your wondering )

[Skepdisc]

@oxide112

9:21

For higher voltages, stick with the resistor.

[ilikepieandthings]

Shouldn't you always use some kind of load to discharge a capacitor? Isn't shorting it out really bad for it?

[pramit9]

Watch in with the subtitles!

[ThedudeVip3r1990]

Amazing, thanks for the explication.

[TakronRust]

Capacitors don't block AC, they block DC. LED's don't light on AC so that's why it went out.

[ARCSTREAMS]

@TakronRust what are you talking about? they block both depeding how they are hooked, I am not sure about led's but in his video it seems he was runing an led of a transformer wich is runned on AC it even shows this in his diagram, now as he connected the cap in series it allowed the led to light, but when he connected the cap in parallel it stoped the AC thus no led lighting.

[TakronRust]

@ARCSTREAMS No they don't block both. You might want to look that up before you start spouting things. I await your blind and pointless rebuttal.

[ARCSTREAMS]

@TakronRust They dont block both at the same time, if you got a simple circuit bat,cap,lightbulb, and you hook them in series the cap will block dc no light, if cap was hooked in parallel it would allow dc thus light on. now if you had AC instead of bat running the light and the cap was in series it would allow the AC thus light on, if cap was hooked in parallel it blocks AC and no light. That is my blind and pointless response, look at his video his statements are correct.

[ARCSTREAMS]

@TakronRust you might want to look up AC driven LED's before you go of spouting things half cocked. lol

[ARCSTREAMS]

@TakronRust I may have stated it wrong by saying they block both, I meant to say they can be made to block DC or AC or allow DC or AC depending on hookup, but your statement was wrong when you said "they dont block AC they block DC" this sounded like the be all and end all of what they can do, then you say the led went out cause they dont run on AC? actually they do there are sum that do, thats why it was working then when he hooked the cap in parallel it went off, don't spout pal.

[torojete]

Thanks C3PO, :) jusk kidding.

[tousisat1]

Very good video. And, that how people could access an electronic device ( Ipod, Computer...) without knowing the password. They just short-circuit all the capacitors and the device will just reset. :)

[SiLeXnet]

Great Video, Thank you!

at 8:24 are you charging the capacitor with alternating current? How would the experiment have been with DC? You cleared everything up perfectly but this one confuses me :D

[1point61803]

If I connect two 30uF capacitors in series, will I get one 60uF capacitor?

[CollPowers]

Everything I did not understand in 2 years in the university... I got in 1 video

[Oshiba88]

Can someone tell me if it’s possible to use an alternative to a 2.2µ 15V?

I can find some capacitors with 2.2µf but they all have a different volts...what does the volt mean btw? Is it how much volt it can hold or how volt it can handle before getting damaged?

I’m playing with a DIY instruction and some parts are hard to find.

A 10K resistor is connected to the 2.2µf 15V cap- is it possible to change the resistor value so that I can use another cap?

[CoolDudeClem]

@Oshiba88 You could replace that cap with a 2.2µ 16V. If you can't find capacitors of the same voltage rating that you need, you can always use one with a higher voltage rating, it does not mean that that cap will always have that voltage when charged. For example, if I charged a 25 volt cap with 9 volts, then that capacitor will have 9 volts in it, not 25.

[pyronathanpyro]

@CoolDudeClem so basicly if i had a 200v capacitor but charged it with 16v it would only go to 16v not 200 ? cheers

[CoolDudeClem]

@pyronathanpyro That's right.

[pyronathanpyro]

@CoolDudeClem brilliant :) i can use my 25v cap on my 16v cdu :)

[MiniFun92]

Sub + thumbs up only.......

[zakeerhussain2009]

good video specially explained clearly about filtering DC and AC, and non-electrolyte values for 3 digits, thnks

[Tranqspogi]

capacitor 104j micro far-rats is useful for Ac to Dc charger

[chazdaspazman]

when i was 12 i worked at my grampas electric motor repair shop and one of his workers gene and i would sneak up on each other discharging high voltage capasitors on each other, it was a shocking but fun experience. lol that's how i learned about caps.

[freethisone]

can you help me, did i discover a new way to charge a ceramic cap, with one wire and a ground only? it will charge and discharge on one current. as long as i have one leg grounded. is this tight? or what?

[00mrjones]

This is one the best tutorial on capacitors.

[pikose78]

Why is it always easy to learn from british people ??????????

[dizzybot]

@pikose78 because they accually try (not saying that some dont)

[bobob0000]

just is great man, you're a great teacher!

[1acroyear1]

Great vid.

Now, what's a farad?

[cam1996reeves]

thanks for the vid, i got some use full info from it.

[magicash23]

Thanks for doing this! I was not interested in this stuff at all way back when in school, but you break this down very well. Inspires me to get into this kind of stuff!

[alexander9619]

"As you can see, the motor is hiting my hand" :) brilliant

[freezzertime]

Just superb.

[DannyT994]

Man. That was something. You should be teaching at MIT...

[vishnukartha47]

Thanks

[orbiter8]

HI Clem,

JFYI, there are many types of capacitor. The most common and widely used is likely the electrolytic type, however others include.. Ceramic, polystyrene, paper, mica, tantalum, mylar and many others with a vast range of capacities & values.

[neo36uk]

great video, very interesting stuff thanks for sharing :-)

[TheMegalucian]

i got a question: how does a capacitor work in a circuit?

[uxsuckx]

Great scot! 1.21 gigawats!?

[ciprianwiner]

nice tutorial, anybody can understand it :D

[foxxxyn]

dude, you are kidding?

only two types?

:D:D

[latropimax]

thanks, very informative.

[twigga91]

great video mate, thanks alot

[Pestisor11]

i love this video!!!

But how it will be used in a circuit(how i discharge that when i put it on a circuit)???When i put the capacitor in series the circuit remain inactive(like it vas off)!!!

When i put the capacitor in paralel nothindg happens!!!!

What i should do???

[CoolDudeClem]

@Pestisor11 Sorry, I cant quite follow you, what exactly is it you're trying to do?

[Pestisor11]

@CoolDudeClem I try to make something that holds the electrical charge and then discharge it afther a short period of time...I want to make a continious cicle of charging and discharging.

[CoolDudeClem]

@Pestisor11 it could be that you're just using a cpacitor that's too small. Rememeber, a larger number on the capactitor basically means it will hold more charge, but the charge in a capacitor will very slowly drain away by itself, even without anything connected.

[Pestisor11]

@CoolDudeClem Ty men. That help alot!!!

[popoqwer]

Brilliant Thank you so Much! now i know, great explanation! Cheers!

[Rannyfash]

thats a lot of farods

[mondays89]

I've never seen someone be s careless with a capacitor... but it is a good thing because I'm trying to learn about them and it helps me to know what I an and can't do. :-)

[giammyzanna]

Why a rectifier is made out of 4 diodes? why it couldn't be made out of 1 diode?

[CoolDudeClem]

@giammyzanna A rectifier can be made with 1 diode, a 1 diode rectifier is known as a "half wave" rectifier because they only do half of the ac cycle.

[giammyzanna]

@CoolDudeClem what about 2 and 3 diodes?

[clydesight]

Very nice video about the two types of capacitors.

Thanks!

[BadEditPro]

How ironic! My heat pump blew a capacitor on Friday. I had to pay big cash to get it replaced on a holiday weekend yesterday. SO, I find it odd you'd decide to do a video about them now. Strange Very informative video! :) JC

[Films4You]

2000% Marks

As you show capacitors allow AC through but stop DC, well nearly, so this is how they can help filter stuff. Hum on audio, electric spikes, etc...

They can be used for timing, very basic, as they take time to charge

[AG3304]

They use a capacitor based system for welding in car factories l believe!Flash bang!Nice video.

[SlimeTron5000]

Great instructions, Clem! As you have covered what I already know for a long time, now.

[umajunkcollector]

What kind of resistor should be used to discharge my flux capacitor that has 88.9 gigawatts of power?

kewl vid!

[trevormeuse16]

@umajunkcollector gigawatts? 0.0

[5lkk]

@umajunkcollector Your body resistance should work just great. Grab a lead in each hand. :)

[Jallge]

thanks clem, stuff was learned

[spannerworks1]

Clem

An excellent lecture and just great many thanks
