NEET Physics RLC Circuits MCQ Question
In a series RLC circuit, under what condition will the amplitude of the current be maximized?
When the frequency of the source is equal to the natural frequency of the circuit.
When the resistance is increased to its maximum value.
When the inductive reactance equals the capacitive reactance but at any frequency.
When the voltage across the inductor is maximum.
Correct Answer
Detailed Explanation
The amplitude of the current in a series RLC circuit is maximized at resonance, which occurs when the frequency of the source matches the circuit's natural frequency, allowing the voltages across L and C to cancel each other.
