Question

In a LCR circuit having L = 8.0 henry, C = 0.5 μF and R = 100 ohm in series. The resonance frequency in per second is

• A. 600 radian
• B. 600 Hz
• C. 500 radian
• D. 500 Hz

Answer 1

Answer: (C)

500 radian

Answer 2

Resonance frequency in radian/second is

$\omega = \frac{1}{\sqrt{LC}} = \frac{1}{\sqrt{8 \times 0.5 \times 10^{- 6}}} = 500rad/sec$
