A small signal voltage V(t) = V 0 sinωt is applied across an ideal capacitor C:
Text Solution
Verified by ExpertsThe correct answer is:
C
When an ideal capacitor is connected with an ac voltage source, current leads voltage by 
. Since, energy stored in capacitor during charging is spent in maintaining charge on the capacitor during discharging. Hence over a full cycle the capacitor does not consume any energy from the voltage source.
