Question
An inductor of 2.5H is connected across a 120V, 60Hz supply. Calculate the current flowing in the inductor.
Correct Answer
Option C is the correct answer.
Detailed Explanation
X_L = 2πfL = 2π×60×2.5 ≈ 942.5Ω, so I = V/X_L = 120/942.5 ≈ 0.13A.
Hint
First calculate the inductive reactance, then apply Ohm's law (I = V/X_L).
