As the title says, just a quick one I could use some help on.
I'm looking through my uni notes and the lecturer has said the power supply needs to be turned off when measuring the winding resistance of a motor. He the put a (why??) after, I'm just not sure why it does? Will the motor draw some current even if it's not turning?
Cheers,
Jake
