In an AC circuit, a resistance of `Rohm` is connected is series with an inductance `L`. If phase angle between volage and current be `45^(@)`, the value of inductive reactance will be

A

`R/4`

B

`R/2`

C

R

D

cannot be found with given data

Text Solution

Verified by Experts

The correct Answer is:
C
`tan phi = (omegaL)/(R) = (X_(L))/(R)`
Given `phi = 45^(@)`. Hence `X_(L) = R`
