A resistor, R = 4„¦, and an inductor, L = 1.3 H, are connected in a circuit to a voltage source as shown in Figure (a) (an RL circuit). 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(-Rt)/L) for 0 i(t) = e-(Rt)/LV/R (e(0.5R)/L -1) for 0.Make a plot of the current as a function of time for 0 :5: t :5: 2 s.
