AIPMT PRELIMS 2007 Physics Resonance in LCR Circuit MCQ Question
Type: MCQ-conceptual-Medium-Class 12
What is the value of inductance L for which the current is maximum in a series LCR circuit with C = 10 µF and ω = 1000s– 1
A
1 mH
B
cannot be calculated unless R is known
C
10 mH
D
100 mH
Correct Answer
Option A
Detailed Explanation
The resonant frequency in an LCR circuit is given by ω = 1/√LC. At this frequency, the impedance is minimum, and the current is maximum.
