AIIMS 2012 Physics Inductive Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
In an AC circuit, voltage V = V₀sinωt and inductor L is connected across the circuit. Then the instantaneous power will be
A
V₀²/2ωL sinωt
B
-V₀²/2ωL sinωt
C
-V₀²/2ωL sin2ωt
D
V₀²/2ωL sin2ωt
Correct Answer
Option C
Detailed Explanation
If dl/dt is the rate of change of current through inductor L of any instant, then induced emf in the inductor of the same instant is -(L dl/dt).
