For an A.C. Circuit, contianing a resistance and a capacitance in series, the angle between current and e.m.f. is given by `tan theta = 1(omega CR)`. The power factor of this circuit is

A

`omega C R`

B

`R/(omega C)`

C

`R/(sqrt(R^(2)+((1)/(omegaC))^(2)))`

D

`R/(sqrt(R+(1)/(omegaC)))`

Text Solution

Verified by Experts

The correct Answer is:
C
`tan theta = 1/((omegaC)/R)`
`:.cos theta = (R)/(sqrt(R^(2)+((1)/(omega C))^(2))`
