If the frequency of an alternating current is doubled while keeping the inductance constant, then the inductive reactance
- A is doubled
- B becomes half
- C remains the same
- D becomes four times
Answer & Solution
Correct Answer
(A) is doubled
Step-by-step Solution
Detailed explanation
\(X_L = 2 \pi f L\) \(X_L' = 2 \pi (2f) L = 2 (2 \pi f L) = 2 X_L\) is doubled
