Electronics (Electrolytic Capacitors) 101

[TV843]

That's like watching the video of the car peacefully driving around in the hills and suddenly the zombie jumps out and screams at you. I'm thinking... When is that thing going to blow?

[prhughes0]

2:00 The 2 series caps may not share the voltage equally without bleeder resistors to overwhelm the difference between leakages of the 2 caps. Especially important with non-electrolytics (like high voltage caps) where unequal leakage currents may allow most of the applied voltage to appear across the less leaky cap, and actually break it down. Equal bleeders of 10x leakage (at rated voltage, temp, etc.) Hope you wear glasses when you pop caps.

that was better than great.5 stars for sure paul!

[kubikop]

Cheers Mate!

[Demoman42]

I see that coming, but it's still make me jump! :D Whats next? |Diods? :)

[kubikop]

Yeah, Ill do one on diodes but I only have standard ones. Ill have to do one on the obscure diodes later...

Paul

ps I knew it was coming and it made me jump too......

[skierplaterandy]

how does your multimeter measure capacitance?

does it work for inductor coils aswell?

[kubikop]

Its not a multimeter its a Capacitance and Inductance meter.

It also measures Transistor NPN and PNP..

So Yeah it works with coils too..

Paul..

[skierplaterandy]

ohhhh so it works specifically with capacitance? thats pretty cool.

[kubikop]

Yeah they are about £20 on ebay, well worth it....

[skierplaterandy]

well i would never really use it much.

i mean it would be handy for coils and stuff, but i mean i dont work with coils much, and caps are normally labeled.

If you are intending this as an educational series, you might want to explain series and parellel connections and even show how to read the ratings and witch side the positive and negative are. It would make it easier to follow for people unfimilliar with this field of enginering.

Nice ending, just had to blow something up eh? LOL!!!

[kubikop]

Yeah, bang!.....lol!

Your right I should have showed that a capacitor has all the information printed on it, including the negative side which has a stripe and a big minus side on it.

I kind of like the thought that it uses Aristotle Style Learning where the people watching will experiment themselves and at least use wiki to learn more on there own.

People do not like to be spoon fed in my opinion and should take an active participation in the process.

Do not take my work for it, try it!

[ZED74]

thankyouuuuu !! useful reference , its in my favorates !! 5/5

[kubikop]

Nice one, glad I could help...

Thanks

Paul..

[Probewitch]

I've heard it said that we learn the most

from mistakes. Hope you didn't get hurt.

[kubikop]

No I did not get hurt, I was wearing eye protection.

I knew it would blow up! I was not expecting the rain of wax though...lol

Its all good and nicely cleaned up... ;-)

I like explosions and high Voltage etc...

Tested to destruction....... its art!

Paul.

[Forssa1]

I was just gonna say to be careful with electrolytic caps because they can easily blow up, but you already know that now, huh? Lol.

[kubikop]

Meant to do it, you will remember this video I am sure....lol

Im going to try and test to destruction every component I look at, like I did with the resistor in the previous video....

Paul..

[AtvProjects]

What Could a 400V capacitor be used for?

[kubikop]

The 400v Capacitors Came out of a 3 Phase Motor Controller.

You could make a Coil Gun out of them...

Paul..

[jupy921]

A good informative video. Nicely done!

[kubikop]

Thanks! It got a little waxy near the end... ;-)

[37474748]

oh so thats what compasitors are used for... put in flames! they make an nice bang :D 5/5

[kubikop]

Thanks!

LOL, oh and you can use them to store voltage also.... ;-)

Paul..

[37474748]

yeah... are they any good for hunting? can you through them at stuff and it gets zapped to death? :D

[kubikop]

Suppose you could make a stun gun and connect it to some chicken fence on the floor?

You may be better off with an air gun?

You should always eat what you hunt though, just my 2 sense though....

Paul..

[valdezmiguel2]

@kubikop real guns work better than air guns/imaginary stun-nets

[kubikop]

I agree....
