A coil of `200Omega` resistance and `1.0H` inductance is conneted to an `AC` source of frequency `200//2pi Hz`. Phase angle between potential and current will be

A

`30^(@)`

B

`90^(@)`

C

`45^(@)`

D

`0^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
`tan phi=(X_(L))/R=(2pivL)/R`
`=(2pixx200/(2pi)xx1)/200=1 implies phi=45^(@)`
