When an alternating current flows through a circuit consisting of a resistor in series with a capacitor, during the cycle at some instant,it is possible to have (a) voltage across the circuit is zero but current through it is not zero.

Options

A. voltage across the circuit is zero but current through it is not zero
B. current through the circuit is zero but the voltage across it is not zero
C. current throught the capacitor is not zero but the voltage across it is zero
D. current throught the resistor is not zero but the voltage across it is zero

Answer

A, B, C

Explanation

As current and voltage are in phase in resistor, so option (d) is not possible, but due to capacitor, all other options are possible as there is phase difference between current and voltages.
