In a circuit consisting solely of an inductor, what happens to the current if the frequency of the supply is decreased to half its original value?

Show Answers

Decrease to half the initial currentIncrease to twice the original currentIncrease to four times the original currentDecrease to one quarter of the initial currentBecome zero

Explanation

In a purely inductive circuit, the inductive reactance (XL = 2πfL) is directly proportional to the frequency. When the frequency is halved, the reactance is also halved, causing the current to double since current I = V / XL.
