The current in and the voltage across a 10 H inductor are known to be zero for t s O. me voltage across the inductor is given by the graph in Fig. P 6.9 for > 0.

a. Derive the expression for the current as a function of time in the intervals 0 t 25 ms, 25 ms t 75 ms, 75 ms t 125 ms, 125 ms t 150 ms, and 150 ms t

b. For t > 0, what is the current in the inductor when the voltage is zero?

c. Sketch i versus t for 0 s t
