Cap. Discharge Res.

Hello,
I was wondering if there is a method of calculating the value and
wattage for the resistor that goes across a mains capacitor to
discharge it once the power has been removed?

What are you trying to accomplish? If you need a safe way to dissipate the
charge on a mains IP reservoir cap, I find a salvaged NTC inrush surge
limiting thermistor from a scrap monitors PSU section works very well. It
starts off with a high resistance before you apply it to the cap terminals
and is heated by the energy discharging from the cap so the resistance
decreases to fully drain the cap.
