Problem 6.24 The two parallel inductors in the following figure are connected across the terminals of a black box at t = 0. The resulting voltage for t > 0 is known to be 64e-4t V. It is also known that 1 (0) = -10 A and 2 (0) = 5 A. (Figure 1) Part A Replace the original inductors with an equivalent inductor and find i(t) for t≥0.
