A coil of self inductance of 1H and resistance 200`Omega` is connected to an A.C. source of frequency `200/pi` Hz. The phase difference between voltage and current will be ...

A

`30^@`

B

`63^@`

C

`45^@`

D

`75^@`

Text Solution

Verified by Experts

The correct Answer is:
B
`delta=tan^(-1) [(omegaL)/R]=tan^(-1) [(2pif. L)/R]`
`=tan^(-1) [(2pixx200/pixx1)/200]`
`=tan^(-1) [2]`
`therefore delta=63^@`
