NEET Physics RLC Circuits MCQ Question
Which of the following statements correctly describe the characteristics of a series RLC circuit at resonance?
The current amplitude is maximized when driven at the natural frequency.
The impedance of the circuit is at its maximum at resonance.
The phase difference between voltage and current is zero at resonance.
The circuit absorbs no power at resonance.
Correct Answer
Detailed Explanation
At resonance, the current amplitude in a series RLC circuit is maximized due to the driving frequency matching the natural frequency of the circuit. The impedance is minimized, and the phase difference is zero, but power is not zero.
