I came across what Looks like a varistor. It definite loooks like a flat and round varistor and brown color. Ot can be wired across a 24 volt ac power supply to a small analogue relay and power it. The relay pulls less than 0.5 amps. The varistor is in series with the relay coil.
The resistance of the varistor is very very small too .But I believe AC varistor at no voltage has a very highresistance.
what could this be?
