Question

An LCR circuit behaves like a damped harmonic oscillator. Comparing it with a spring-mass oscillator of mass m, spring constant k and damping constant b, the correct equivalence is:

G1 Physics · Accepted Answer

Compare Lq¨+Rq̇+q/C=0 with mx¨+bẋ+kx=0. Thus L↔m, R↔b and 1/C↔k, i.e. C↔1/k. Hence option A.
