If you had a 100pF 50kv doorknob cap you could make a useful high voltage divider, of course you would have to make a stand for the whole thing, I'm sure that capacitor is relatively heavy.

Hi Hazmatt_(The Underdog)

I think to build up a voltage divider for AC by capacitors is a good idea.

"If you had a 100pF 50kv doorknob cap you could make a useful high voltage divider".

Using your 100pF 50kv doorknob cap and my 10nF cap, the 100 pF should be at the high voltage side.
To divide a voltage of 200 kV down to 100 V (2000:1) you would need a capacitor at the low voltage side of 20uF.

I get things mixed up from time to time.

It's been 10 years since I built a capacitor divider.

Similar to a battery of Leyden jars. Good for classical experiments as exploding wires. Don't take a shock from it.

This capacitor´s mass is 18.5 kg, the length is 110 cm and the diameter is 14 cm.
