Chapter 6, Problem 10P

a.

To determine

Derive the expressions for current i as a function of time for the intervals $0\le t\le 1\text{s},1\text{s}\le t\le 3\text{s,}3\text{s}\le t\le 5\text{s,}5\text{s}\le t\le 6\text{s,}\text{and}6\text{s}\le t\le \infty$.

b.

To determine

Calculate the current in the inductor when the voltage across the inductor is zero.

c.

To determine

Plot the graph of i versus t for $0\le t\le \infty$.
