Any suggestions on a 1 billion volt capacitor? the smallest i can make it is needed.?

Question

or 1 that i can buy...

Answer 1

I'm curious as to what you plan to do with such a device.

As an example, say you come in here asking how to use a jackhammer. We ask why, and you say it's to knock your grandmother's  head off to let out the evil spirits that gave her cancer. So maybe the problem is actually unrelated to jackhammers. Or billion volt capacitors for that matter.

Answer 2

Capacitors are measured in Capacitance or Faradays, not Voltage

Answer 3

Anything above several 100 kV is impossible, as that voltage will flash over between the electrodes.

Breakdown in air is about 33 kV/cm. At 1 million volts, you need air gaps of 30 cm. At 1 billion volts, you need air gaps of 300 meters.

Try building a capacitor where the wires and the plates are 300 meters apart. Not just from each other, but also from everything else.

good laugh tho!!

Answer 4

And where do you think you'll get the billion volts to charge it?  It would be really big.  The insulating ability of dry air is about 3000V/mm, which means for a billion volts the capacitor plates would need to be 333 meters apart.  Now go play some more Xbox.

Answer 5

You can get 100 volt capacitors from digikey.com. Connect 10 million of these in series, and pot the assembly in magic epoxy (you know, the stuff that DuPont doesn't make that will withstand one billion volts). Remember that the capacitnce value gets divided by 10 million, so a 1uF capacitor will give you a capacitance of 0.1pF in total.

To make a one trillion volt capacitor, simply multiply the number of capacitors by 1000.
