Meters and troubleshootingQuestion 713 of 1506

One resistor in a series-parallel circuit increases in value because of overheating. What happens to the total circuit resistance?

It becomes zero
It increases
It stays the same
It decreases

Show answer

Correct answer: It increases

A single resistor that rises in value makes the total rise too, and the other way around.
