The switch S is closed at t = 0. the capacitor C is uncharged but `C_0` has a charge `q_0` at `t =0`. Calculate the current `i(t)` in the circuit

A

`[(E-(q_(0))/(C_(0)))/(R )]e^(-(t)/(RC_(eq))`

B

`(E )/(R )(e^(-(t)/(RC_(eq))))`

C

`(q_(0))/(C_(0))[e^(-(t)/(RC_(eq)))]`

D

`[(E+(q_(0))/(C_(0)))/(R )]e^(-(t)/(RC_(eq))` where `C_(eq)=(C_(0)C)/(C_(0)+C)`
