Electro Magnetic Induction And Alternating Currents Question 21

Question: In a LCR circuit having L = 8.0 henry, C = 0.5 mF and R = 100 ohm in series. The resonance frequency in per second is [CPMT 1990]

Options:

A) 600 radian

B) 600 Hz

C) 500 radian

D) 500 Hz

Show Answer

Answer:

Correct Answer: C

Solution:

Resonance frequency in radian/second is $ \omega =\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{8\times 0.5\times {{10}^{-6}}}}=500rad/sec $
