If the frequency of an alternating current is doubled while keeping the inductance constant, then the inductive reactance

is doubled

The correct answer is Option (1) → is doubled

Inductive reactance is given by:

$X_L = 2 \pi f L$

If frequency is doubled:

$X_L' = 2 \pi (2f) L = 2(2 \pi f L) = 2X_L$

Answer: The inductive reactance becomes double.
