NEET2016Physics-Voltage across Capacitor
NEET 2016 Physics Phase angle MCQ Question
Type: MCQ-conceptual-Easy-Class 12
A small signal voltage V(t) = V₀ sinωt is applied across an ideal capacitor C
A
Current I(t) is in phase with voltage V(t).
B
Current I(t) leads voltage V(t) by 180°.
C
Current I(t) lags voltage V(t) by 90°.
D
Over a full cycle the capacitor C does not consume any energy from the voltage source.
Correct Answer
Option D
Detailed Explanation
In an ideal capacitor, the current leads the voltage by 90°, and over a full cycle, the net energy consumed is zero as energy is stored and released.
