For the network in given figure, V₁(t) is the input and i (t) is the output. The transfer function l (s)/V_i (s) of the network is—

1. Cs
  RCs² + RCs + 1
2. C
  RCs² + RCs + 1
3. Cs
  RCs² + LCs + 1
4. C
  RCs² + LCs + 1

Correct Option: A

Given series circuit

I(s)	=	1
V_is	=	R + Ls + 1/Cs

or,

I(s)	=	1
V_is	=	RCs + LCs² +1
