NEET 2026 Physics Resonance in AC Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
An ac circuit contains a resistance of 1 kΩ, a capacitor of 0.1 μF and an inductor of 1 mH connected in series. The resonance frequency of the circuit is approximately:
A
13.5 kHz
B
10.1 kHz
C
20.7 kHz
D
15.9 kHz
Correct Answer
Option D
Detailed Explanation
The resonance frequency f₀ is calculated using the formula f₀ = 1 / (2π√(LC)). Substituting L = 1 mH and C = 0.1 μF, we get f₀ ≈ 15.9 kHz.
