1. (50 pts) Inductor. A triangular current pulse is applied to a 400 mH inductor, as shown below a. Write expressions that describe i(t) in four intervals: t < 0,0

< t< 25 msec, 25 msec < t< 50 msec, and t > 50 msec. b. Derive the expressions for the inductor voltage, power and energy. c. Draw your results similar to the graph on the next page, making sure the times are aligned vertically.
