A series `AC` circuit consists of an inductor and a capacitor. The inductance and capacitance is respectively `1`henry and `25 muF` if the current is maximum in circuit then angular frequency will be

A

`200` rad/s

B

`100` rad/s

C

`50` rad/s

D

`200//2pi` rad/s

Text Solution

Verified by Experts

The correct Answer is:
A
Current in `LC` circuit becomes maximum when resonance occurs. So,
`omega=1/(sqrt(LC))=1/(sqrt(1xx25xx10^(-6)))=1000/5=200rad//sec`
An alternating e.m.f of frequency is `v(=1/(2pisqrt(LC)))`
