Angry microwave oven capacitors

Well, I charged them (total of 23) just 2,82kVDC with a mot and single wave rectifier. Energy : only 91 J. I'm sure, those capacitors can be charged up to 8kVDC! On 8kV they store 736J.

Where do you get all those capacitors? I notice they are the same type...

[omegalab]

@a380rockerfan I have 200 of these capacitors, I bought them from a friend.

[jeffddow]

maybe its your camera but why do the blue caps on top seem like they have a residual glow afterwards?

[omegalab]

@jeffddow The intense UV light from the sparks charge the cap's envelope material, and it has a very little afterglow. Most of the plastics have this effect, I have similar experience with a polyamide rotating spark gap, which emitted green light.

is it posible to use microwave capasitors for low voltage like 12volts dc? in that case how? I would like to get a few and make an bank of caps :)

[omegalab]

@37474748 Of course it is possible, but what is your goal with this? 1uF 2100V caps charged to 12V has a total energy of 0,000072 J. With this energy you even can't light up a LED for more than a few milliseconds.

hahaha fuck. if you had one of those capacitors wired to your window wipers ud stop getting tickets eh haha. jokes

[omegalab]

@FelSound You need to learn the ohm's law first, trust me ;)

@MrStemkilla my first tesla coils used a bank of saltwater caps ,i used a lot of jars to make a very small 14nf in total but because thay run ac they charge and discarge 100 times a second which is the same time as the spark gap which all run at the same time as the line frequency 50 Hz .i now have a mmc its still 14 nf but alot smaller .check out my vids of them ?!

[MrStemkilla]

@jsiuksta well im planing to use a different kind of cap i wanted to use a metal plate inolated by a big rubber matt then repeat the proses several times so hopefully that will create a way better cap but maby if i can get some diodes and maby i can make it a dc cap to get a better charge idk maby my i will do that for a second coil

[jsiuksta]

@MrStemkilla Assuming we're talking about home made Leyden Jar capacitors, (glass jar, salt water inside, aluminium kitchen foil glued to the outside) with very little capacity, then one cycle should be enough to charge them up. Although I have seen Tesla Coil plans with DC-charged capacitors. I have built a Leyden Jar, but not a Tesla Coil, so I can't really speak from experience about Tesla coils. My interest is in building a replica of the E.V. Gray motor, which is high voltage DC powered.

[MrStemkilla]

@jsiuksta that rases the qwestion how do tesla coile capacitors chatge if they will only hold one sycoles worth of electrons?

[jsiuksta]

@MrStemkilla My guess is that it's a Smoothing Capacitor. That is it smooths out the wave-form of the output from the transformer. So that when the transformer voltage temporarily goes to zero, the capacitor feeds it's packet of stored energy to the Magnetron. But this is just a guess. My Google searching didn't provide a specific answer.

[MrStemkilla]

@jsiuksta thats what im saying the output is ac and the magnetron runs on ac then why is there a cap in between and if its being fed ac like you said it shouldent be charging but why dould the put it in there if its not doing anything?

[jsiuksta]

@MrStemkilla Well having studied the wiring diagram for a Toshiba microwave, It looks like the capacitor (the only one I could see in the diagram) is part of the voltage step-up system, that feeds the Magnetron. That's why its voltage rating would be in AC. The output from the secondary coil of a transformer is always AC.

[MrStemkilla]

@jsiuksta ok i see thats sorda what i thought but then how do microwaves charge thir caps? and why is it rated for ac?
