Question

Let frequency v = 50 Hz, and capacitance C = 100μF in an ac circuit containing a capacitor only. If the peak value of the current in the circuit is 1.57 A. The expression for the instantaneous voltage across the capacitor will be

Answer 1

The correct option is (a).

Explanation:

Peak value of voltage

Hence if equation of current i = i_o sin ω t then in capacitive circuit voltage is
