For Fig. 1:

a. Determine the mathematical expressions for iL and υL following the closing of the switch. Note the defined direction for iL and polarity for υL.

---

b. Calculate iL and υL at t =10 μs.

---

c. Write the mathematical expressions for the current iL and the voltage υL if the switch is opened at t = 10 μs.

---

d. Sketch the waveforms of iL and υL for parts (a) and (c).
