A current of `25/pi` Hz frequency is passing through an A.C. circuit having series combination of R = 100 `Omega` and L =2 H, the phase difference between voltage and current is …

A

`90^@`

B

`60^@`

C

`30^@`

D

`45^@`

Text Solution

Verified by Experts

The correct Answer is:
D
`tan delta=(omegaL)/R=(2pifL)/R=(2pixx25/pixx2)/100`
`therefore tan delta=100/100=1`
`therefore delta =45^@`
