The voltage measured across the inductor in a series RL has dropped significantly from normal. What could possibly be the problem?
A)The resistor has gone up in value.
B)partial shorting of the windings of the inductor
C)The resistor has gone down in value.
D)either A or B

Question

Quizplus · Accepted Answer

The voltage across an inductor in a series RL circuit is directly proportional to the current flowing through it. If the voltage has dropped significantly, it could be due to a decrease in current. This could be caused by an increase in the resistance of the circuit (choice A) or a partial shorting of the windings of the inductor (choice B).
