I have 1280uf 200v capacitor in a circuit. The input is variable between 1vdc and 108vdc, 1vac and 120vac. Amperage is less than 1A. When I turn the variable transformer down, it takes a long time to drop the voltage. I have a 100w 100ohm resistor that drains the power. It is currently on a momentary switch that I push to drain the cap. Can I user a smaller resistor and have it on all the time to both give a small load(around 250ma) and drain the capacitor so I can change voltage quicker?
1. Caps don't care whether AC or DC, correct? Or am I gonna blow this thing up?
2. How big of a resistor do I need to drain the voltage in a couple seconds?
C. How do I find a list of my previous posts and/or threads?
