An alternating e.m.f. is applied to a circuit containing an inductance and a capacitance in series. It is found that for a particular frequency 'f' of the A.C. Genrator, the current in the circuit is maximum. If `L=1/(2 pi)` Henry and `c = 1/(2pi) muF`, then the reasonant frequency is

A

100 Hz

B

1000 Hz

C

500 Hz

D

50 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`f = L/(2 pisqrt(LC)) = 1/(2pisqrt(1/(2pi)xx1/(2pi) xx 10^(-6)))`
`= 10^(3) = 1000 Hz`.
