When the voltage source applies a rectangular voltage pulse with an amplitude of V=
12 V and a duration of 0.5 s, as shown in Figure (b), the current i(t) in the circuit as a
function of time is given by:
i(t) = (V/R)(1-e(-RO)/L) for 0<t < 0.5 s
i(t) = e (R)/L (V/R)(e(0.SR)/L -1) for 0.5<ts
Make a plot ofthe current as a function of time for 0<t<2 s.
