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 = tan 45^@ = (X_L)/(R )`
`therefore X_L = R`
