RE-NEET 2026 Physics LCR Circuits MCQ Question

Type: MCQ-numerical-Medium

An ac voltage V=220 sin(2×10³t) Volt is applied to a series LCR circuit. Then the current amplitude in this circuit is : (Given : L=10 mH, C=25μF, R=100 Ω)

A

5.5 Å

B

11.0 Å

C

22.0 Å

D

2.2 Å

Correct Answer

Option D

Detailed Explanation

The impedance Z of the LCR circuit is calculated using Z = √(R² + (ωL - 1/ωC)²). Substituting the given values, the impedance is found, and the current amplitude I = V₀/Z is calculated to be 2.2 Å.
