RE-NEET 2024 Physics Inductors in AC Circuits MCQ Question
Type: MCQ-conceptual-Medium-Class 12
In the circuit shown below, the inductance L is connected to an ac source. The current flowing in the circuit is I = I₀sinωt. The voltage drop (Vₗ) across L is
A
ωL I₀sinωt
B
I₀/ωL sinωt
C
I₀/ωL cosωt
D
ωL I₀cosωt
Correct Answer
Option D
Detailed Explanation
The voltage across an inductor is given by Vₗ = L(di/dt). Differentiating I = I₀sinωt gives di/dt = ωI₀cosωt. Therefore, Vₗ = ωL I₀cosωt.
