A small signal voltage V(t) = V 0 sin t is applied across an ideal capacitor C.
Physics · Class 12 · CBSE — Alternating Current
A small signal voltage V(t) = V0 sin t is applied across an ideal capacitor C.
- Current I(t) lags voltage V(t) by 90o
- Over a full cycle the capacitor C does not consume any energy from the voltage source.
- Current I(t) is in phase with voltage V(t)
- Current I(t) leads voltage V(t) by 180o.
Answer
(B) Over a full cycle the capacitor C does not consume any energy from the voltage source.
