Chapter 11, Problem 25P

For Fig. 11.92:

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

b. Calculate i_L and v_L at $t\text{ = 10}\mu \text{s}\text{.}$

c. Write the mathematical expressions for the current i_L and the voltage v_L if the switch is opened at $t\text{ = 10}\mu \text{s}\text{.}$

d. Sketch the waveforms of i_L and V_L for parts (a) and (C).
