NEET Physics RLC Circuits MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about RLC circuits is correct?
A
In a series RLC circuit, the current reaches maximum amplitude at the natural frequency.
B
The energy stored in the capacitor and inductor remains constant at all times during oscillation.
C
Resonance occurs when the impedance of the circuit is at its maximum.
D
The phase difference between current and voltage is always zero at resonance.
Correct Answer
Option A
Detailed Explanation
At resonance in a series RLC circuit, the current indeed reaches its maximum amplitude when driven at the natural frequency, as the circuit exhibits a tendency to oscillate at this frequency. Other options contain misconceptions about energy conservation and phase relationships.
