In a series RL circuit, the resitance and inductive reactane are the same. Then the phase difference between the voltage and current in the circuit is

A

`pi/4`

B

`pi/2`

C

`pi/6`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
In RL circuit
`tanphi=X_(L)/R`
If `X_(L)=R" "then, tanphi=R/R=1`
`thereforephi=tan^(-1)(1)=pi/4`
phase difference `=pi/4`
