A capacitor and resistor are connected with an `AC` source as shown in figureure. Reactance of capacitor is `X_C=3Omega` and resistance of resistor is `4Omega`. Phase difference between current `I` and `I_1 is [tan^-1(3/4)=37^@]`
.

A

`90^@`

B

zero

C

`53^@`

D

`37^@`

Text Solution

Verified by Experts

The correct Answer is:
C
`I_2=V/X_C=V/3` (here V=rms value)
`I_1=V/R=V/4`
`I_2` is `90^@` ahead of applied voltage function and `I_1` is in phase with it.

`I_1=V/4`
`tanphi=(V//3)/(V//4)=4/3`
`:. phi=53^@`
