Question

An inductor of 2.5H is connected across a 120V, 60Hz supply. Calculate the current flowing in the inductor.
Options
A 0.13A
Correct Answer
B 1.52A
C 0.06A
D 13.8A
Correct Answer

Option A is the correct answer.

Detailed Explanation

X_L = 2πfL = 2π×60×2.5 = 942.5 Ω. I = V/X_L = 120/942.5 ≈ 0.127 A ≈ 0.13 A.

Hint

I = V/(2πfL).
