Default Using a capacitor as a "wattless" dropper on 110 volt equipment?

C dropping never handled any Watt's incidentally, the clue is in
"Wattless dropper".

C droppers pass plenty of watts. They just don't dissipate them.

P = V^2/ R


precisely, so approximately no dissipation, despite it passing plenty of watts to whatever's downstream.

Rubbish!

It passes no Watts.

The only time a capacitor will "pass" Watts is when it heats up.

Current is Amps, not Watts


If a capacitor had anything to do with Watts, you would specify said
value on ordering.

Please point out where you would buy a 10uF 5 Watt capacitor.

Oh dear.
