New to building circuits, I''m trying to develop an understanding as to when a bleeder resistor should be connected across a capacitor for safety reasons. I''ve seen several references talking about how quickly the bleeder resistor should reduce voltage (usually 5T), under what threshold the bleeder should reduce voltage (either 50V or 60V, …

How can a MOSFET can be used as resistor and capacitor
By applying a gate voltage lower than a MOSFET''S Vgson but higher than it''s minimum conduction threshold, you will cause it to have a resistance higher than it''s Rdson and lower than it''s off state resistance, and in this way, you can use it as a variable resistor, with dissipation capability determined by chip specs, packaging and cooling.
