Question

With increase in frequency of an A.C. supply, the inductive reactance

• A. decreases
• B. increases directly with frequency
• C. increases as square of frequency
• D. decreases inversely with frequency

Answer 1

Answer: (B)

increases directly with frequency

The inductive reactance $X_l=\omega L$

Hence, $X_l\propto \omega$

As frequency increases $\to \omega$

Therefore, inductive reactance increases with frequency.
