An A.C. source is connected to a resistive circuit, current …….

A

lags behind voltage in phase

B

and voltage are in the same phase

C

leads ahead to voltage in phase

D

in first half cycle it leads ahead to voltage and remain first half it lags behind voltage in phase.

Text Solution

Verified by Experts

The correct Answer is:
B
For the circuit having only resistance `delta= 0` so current and voltage is in the same phase.
