In one series A.C. circuit, maxima of current and voltage occur at the same moment. Then which of following component must have been connected to source ?

A

Only resistor

B

Only inductor

C

Only capacitor

D

Series connection of inductor and capacitor

Text Solution

Verified by Experts

The correct Answer is:
A

Because tan `delta=(X_L-X_C)/R=0`
(`because` For only resistive circuit , `X_L=X_C=0`)
`therefore delta=0`
`therefore I_m` and `V_m` are obtained at the same moment.
