Hi Gary,
I have a variac and want to make an ammeter for it. I played around a little trying to get some voltage to power the meter by wraping a wire around one of the output leads but didnt have much success. I also tried using a low value output resistor and geting the voltage drop across it. This worked but i would hve to rectify the voltage to use a dc meter and im afraid that the voltage drop of a diode would make this impossible. What would you suggest?
