The current in a 20 mh inductor is known to be: i = 40 ma for t ≤ 0 i = a1e−10,000t + a2e−40,000t a for t ≥ 0 where t is in seconds. the voltage across the inductor (passive sign convention) is 28 v at t = 0. a) find the correct expression for the voltage across the inductor for t > 0. b) find the time, greater than zero, when the power at the terminals of the inductor is zero.
