- 5 kHz
- 10 kHz
- 15 kHz
- 20 kHz
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The impedance of an RLC circuit is minimum when the frequency is such that the inductive reactance equals the capacitive reactance. From the given values, we calculate the frequency for which the impedance is minimized to be 10 kHz.
Thus, the correct answer is option (2).
