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.
