A coil with an inductance of 0.2 H has an inductive reactance of \( 62.8 \, \Omega \) at a certain frequency. The frequency is
- A 20 Hz
- B 30 Hz
- C 40 Hz
- D 50 Hz
Answer & Solution
Correct Answer
(D) 50 Hz
Step-by-step Solution
Detailed explanation
\( f = \frac{X_L}{2 \pi L} \) \( f = \frac{62.8}{2 \pi (0.2)} \) \( f = 50 \, \text{Hz} \)
