QNEET-2016-Ph-1088: NEET 2016 Physics - Class 12 NEET-2016-Ph-1088 Solution: A small signal voltage $V(t) = V_0 t$ is applied across an…

A small signal voltage

V(t) = V_0\sin\omega t

is applied across an ideal capacitor C Current I(t) is in phase with voltage V(t). Current I(t) leads voltage V(t) by

180^\circ

Current I(t) lags voltage V(t) by

90^\circ

. Over a full cycle the capacitor C does not consume any energy from the voltage source.

A Current $I(t)$ I ( t ) is in phase with voltage $V(t)$ V ( t ) .
B Current $I(t)$ I ( t ) leads voltage V(t) by 180 o
C Current $I(t)$ I ( t ) , legs voltage $V(t)$ V ( t ) by 90 o .
D Over a full cycle the capacitor C foes not consume any energy from the voltage source.

Step-by-Step Verified Solution

In ideal capacitor, I leads from voltage by 90 o and capacitor does not consume energy.
