How to size a rheostat
Web1) choose precharge time as you like (I suggest 1-3 sec) and calculate resistor value keeping in mind that it takes 3 time constant to fully charge the capacitors. 2) To size resistor wattage... WebOct 11, 2012 · Basically, you can use the clipped off terminal from just about any passive component as a jumper that will handle more than 200 mA. 22 gauge wire is about 25 mils thick and will take 7 amps. That's still thin enough to fit through 25 mil holes on a PCB, so why not use something close to that size. The less resistance, the better.
