Question

A LCR circuit behaves like a damped harmonic oscillator. Comparing it with a physical spring-mass damped oscillator having damping constant 'b', the correct equivalence would be:

Answer 1

Answer is (1) 

In damped oscillation

ma + bv + kx = 0

Comparing equation (i) and (ii)

m = L, b = R, k = 1/c 

Answer 2

Answer is

 

for damped oscillator

net force = – kx – bv = ma
