Physics-Resonance
NEET Physics Resonance MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a series RLC circuit connected to an AC source. Describe a setup where a variable capacitor is used to achieve resonance in this circuit. What happens to the current amplitude when resonance is achieved?
A
The current amplitude reaches its maximum value.
B
The current amplitude becomes zero.
C
The current amplitude reaches its minimum value.
D
The current amplitude becomes infinite.
Correct Answer
Option A
Detailed Explanation
Resonance in an RLC circuit occurs when the capacitive and inductive reactances cancel each other, leading to maximum current amplitude as described in the NCERT context.
