Homework Help: Phys

The value of a real-world resistor ______ changes with significant time as the resistor conducts a current.

never
rarely
sometimes
usually

I think either never or rarely, but I'm not sure. When you unplug the resistor, the Ammeter and Voltmeter reading goes down to 0 because you disrupt the electrical current, but I don't know in regards to this question.

Thanks you for your help!
