Fun with capacitors! PICS!!!

<< And how many farads is that? Farads are the measure of capicatance, not volts. >>



Most capacitors have an voltage rating on them meaning to how many volts it can charge up to before the cap blows off. Can't remember how many Farads because it was too long ago.

Two ways of making capacitor go booomm

1. ) Apply a voltage exceeding the maximum voltage rating of a capacitor.

2.) Charge up a capacitor to close to the maximum voltage, remove the capacitor with a needle nose. apply the tip of the capacitor to an conducting surface and watch the fireworks fly! This won't blow up the capacitor so it's fun to do over and over again.

<< Thats NOTHING compared to my caps. One of my capacitor combo is 6mF, 300V and it stores 270joules. Short them out like that and you will instantly
render the tip of the screw driver useless and it pops so loud it wouldn't hurt to wear a hearing protection. >>



who cares about the capacitor, somebody has a 300V power supply.

<< can somebody tell me why that happenes? >>


You know what a capacitor is?

6mF, 300V and it stores 270joules :Q

Where do you get those big caps? I had a 1mF cap that I was using for an experiment a few weeks ago, and would have loved a bigger one. I'm just not sure where to buy circuit components ...

jebus you confused the heck out of me with that smiley linkage

you might be able to find one at http://www.mpja.com/ or your friendly radio shack

couldn't find the link :|

Nice.

The link is in the smiley or where it says pic on my server(or something close to that, i don't feel like looking)

If you need 300v so badly, use a circuit like this:

I use it to charge the caps for my coilgun. C2 is your big capacitor of choice. Make sure you use BIG diodes if you want to charge at any significant rate. The big fat resistor is there because otherwise the cap will charge in 2 seconds or less, putting a noticable strain on the house wiring.

And now... a real practical use of Capacitors...

Ohhh almost forgot this one... NOW... thouse are some Capacitors
