WebMay 28, 2024 · In the rheostat you might be dissipating 12 Amps of current to get down to 1-2 volts and that current level. That looks like megaoverkill to me, but hey you're free to waste resources until there are no more. ElectricSpidey Joined Dec 2, 2024 2,281 May 28, 2024 #5 Why would you use a 150 watt supply when your process only requires .6 watts? 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.
