In an `AC` circuit, the reactannce is equal to the resistance. The power factor of the circuit will be

A

1

B

`1/2`

C

`(1)/(sqrt2)`

D

0

Text Solution

Verified by Experts

The correct Answer is:
C
`tan phi = X/R =1 rArr phi = tan^(-1) (1) = 45^@`
Power factor = `cos phi = cos 45^@ = (1)/(sqrt2)`
