(a) Use the Laplace transform to find the current i(t) in a single-loop LR-series circuit when i(0) = 0, L = 1 h, R = 10 Ω, and E(t) is as given in Figure 7.3.21.

(b) Use a computer graphing program to graph i(t) for 0 ≤ t ≤ 6. Use the graph to estimate i_max and i_min, the maximum and minimum values of the current.
