NEET Physics RLC Circuits MCQ Question

Type: MCQ-conceptual-Hard-Class 12

In a series RLC circuit, under what condition will the amplitude of the current be maximized?

A

When the frequency of the source is equal to the natural frequency of the circuit.

B

When the resistance is increased to its maximum value.

C

When the inductive reactance equals the capacitive reactance but at any frequency.

D

When the voltage across the inductor is maximum.

Correct Answer

Option A

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.
