# Control Systems HW question?

Please refer to picture, I don't understand this problem (with the exception of a), and would like an explanation of work/answer, anything helps!

(b) Using the equation above, find the transfer function from the input voltage vi(t)and the current i(t);

i.e. find I(s)/Vi(s).

(c) Assume that vi(t) = 0 for t >0 and i(0) =/= 0 . Does i(t) tend to zero as t→∞? Justify.

I/v=1/ (R+Ls+1/cs)

of course i(t) will go to zero if the input voltage is zero in positive time.Eventually the cap will discharge and current will stop
