What will be the self-inductance of a coil, to be connected in a series with a resistance of `pi sqrt (3) Omega` such that the phase difference between the e.m.f. and the current at `50 Hz` frequency is `30^@`?

A

`0.5` Henry

B

`0.03` Henry

C

`0.05` Henry

D

`0.01` Henry

Text Solution

Verified by Experts

The correct Answer is:
C
`tan varphi=(X_(L))/R=(2pivL)/R`
`implies tan 30^(@)=(2pixx50xxL)/(pisqrt(3)) implies L=0.01 H`.
