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.
Express your answer in terms of t, where t is in seconds.
