I have a circuit with a voltage of about 150 volts but with just about 1.75 mA current draw. Will I be alright with a 1K, 3K or 5K 1/2 watt or a 1 watt potentiometer to adjust and dial in the voltage? This is sometimes nice for a microphone in order to get the desired sound. I would of course rather use a 5 watt potentiometer but I will need to order one.
What kind of power rating do I need for a potentiometer if I run 150V across it?
