Question

On comparing the oscillation of damped oscillations
of mechanical system with those in parallel RLC
circuit connected to external source. The damping
coefficient is found to be analogous to :-
R
(1) -
(2) R
(3)
I (4) Tc.​

Answer 1

Explanation:

The circuit forms a harmonic oscillator for current, and resonates in a similar way as an LC circuit. Introducing the resistor increases the decay of these oscillations, which is also known as damping. The resistor also reduces the peak resonant frequency. ... RLC circuits have many applications as oscillator circuits.
