We wish to determine the current through the circuit i(t) considering the applied voltage v(t) and
the initial current in the inductor io using the Laplace transform. Follow the steps below.
(a) Write the differential equation relating i(t) and v(t). At this time the values of t1 and t2 do not
need to be specified.
(b) Take the Laplace transform of (a) considering the initial current in the inductor.
(c) Solve for the current using the inverse Laplace transform.
