Current of 50/`pi` Hz frequency is passing | through an A.C. circuit having series combination of resistance R = 100`Omega` and inductor `L = sqrt3H`. The phase difference between the voltage and current is …..

A

`30^@`

B

`45^@`

C

`60^@`

D

`90^@`

Text Solution

Verified by Experts

The correct Answer is:
C
`tan phi=(WL)/R` [L-R series of circuit]
`=(100xxsqrt3)/100`
`f=50/pi rArr 2pif =100`
`therefore (omega)` = 100 rad/sec
`=sqrt3`
`= phi=60^@`
