Of course, at DC, a capacitor doesn’t conduct any better than the insulator used as its dielectric. However, a DC voltage has to start sometime and when it does, it briefly looks like AC.

Capacitors connected from line to neutral provide reactive power to an AC circuit, which is measured in volt-amperes reactive (VARs). For a given value of capacitance, more VARs are supplied as the ...

On the October 14, 2024, a design idea (DI) by Nick Cornford entitled “ To press ON or hold OFF? This does both ” appeared. It is a very interesting DI for DC voltages, but what about AC voltages? Wow ...
