An inductor supplied with 50 V ac with a frequency of 10 kHz passes a current of 7.96 mA. The value of inductor is
- A. 1 mH
- B. 10 mH
- C. 100 mH
- D. 1 H
Answer: C. 100 mH
Explanation: Using the relation $V=IX_{L}$, we get $50 = 7.96\times10^{-3} \times 2\pi \times 10^{4} \times L$. Solving for L gives $L = 99.97\text{ mH}$, which is approximately 100 mH.
