Which one is correct?

Dear Sayan, Here is your complete solution.

option a is correct...

Damping represents presence of resistance in RLC circuit.In a pure LC circuit oscillation occuurs for indefinite time. The circuit oscillates if the resistance is zero.However RLC ...

Current in the circuit depends on value of R,L and C.Let us define two quantity b=R/2L and w=√(1/LC). Now 1.if b>w then circuit is called over damped. 2.if b=w then circuit is cal...
