How to discharge a high voltage capacitor?

Question

Electronics

How to discharge a high-voltage capacitor, for example, a 2100V capacitor in a microwave. Capacitors with a small voltage can be closed with a screwdriver, but screwdrivers are mainly rated up to 1000 volts, and at this voltage it can also be pierced through a screwdriver? Or will she melt?

Answer 1

In no case should you discharge high-voltage capacitors with a screwdriver - they will not deteriorate immediately then, only pulse capacitors are designed for this disgrace, and the number of such discharges is limited.
the time it takes to discharge the capacitor to 1% of the initial voltage 5RC if we assume you need to discharge 2 kilovolts 0.1 microfarads in 10 seconds (there is so much in the microwave), then this is 20 MΩ,
2 MΩ, respectively, will be 1 second - there will still be a spark) and and Yes, 0.125 watts is enough - the resistor will not have time to heat up.

Answer 2

Lick (of course, this is a joke, you should not do this)

Answer 3

Through resistance.
Offhand resistance from hundreds of kilo-ohms 0.125 W should be enough.

Answer 4

light a candle, place the plus and minus of the capacitor on the sides of the candle flame, leave it like that for ten minutes.
