Q. In a $LCR$ circuit having $L = 8.0\ henry,\ C = 0.5\ \mu F$ and $R = 100\ ohm$ in series. The resonance frequency in per second is
A) 700 $radian$
B) 600 $Hz$
C) 500 $radian$
D) 500 $Hz$
Explanation
(c) Resonance frequency in $radian/second$ is
$\omega = \frac{1}{\sqrt{LC}} = \frac{1}{\sqrt{8 \times 0.5 \times 10^{- 6}}} = 500\ rad/sec$
