STANDARD Physics Inductive Reactance MCQ Question
Type: MCQ-numerical-Medium-Class 12
A 44 mH inductor is connected to 220 V, 50 Hz ac supply. The rms value of the current in the circuit is
A
12.8 A
B
13.6 A
C
15.9 A
D
19.5 A
Correct Answer
Option C
Detailed Explanation
The inductive reactance is calculated using Xₗ = 2πfL. Substituting the given values, Xₗ = 2 × 3.14 × 50 × 44 × 10⁻³ = 13.82 Ω. The rms current Iₘₛ = Vₘₛ / Xₗ = 220 / 13.82 = 15.9 A.
