Thank you for the breakdown. I'm doing an electromechanical technician course and the bleeder resistor had me a little lost. Now I have to try to get my head around a Cermet-film resistor.

What value resistor should a use with a 50V, 47,000uF capacitor? I'm using the capacitor in a welder that has an operating voltage of about 35V. Cheers

What will be the value of this bleeder Resestor ?

One has to compromise between power consumption and the speed of bleeder resistor. A small valued resistor can provide high speed bleeding but the power consumed is higher. So it is up to the designer that how much manipulation does he wants. The resistor value must be high enough to not interfere with power supply and at the same time low enough to discharge the capacitor quickly. The formula to calculate the value of bleeder resistor is given as: R = -t/C*ln(Vsafe/Vo) Here t is the time taken by the capacitor to discharge through bleeder resistor R is the resistance of bleeder resistor C is capacitance of the capacitor Vsafe is the safe voltage up to which it can be discharged Vo is initial voltage of the capacitor

@@susendramadallapalli7957 Also, for Vsafe, is it referring to the maximum voltage of the capacitor?
