Question

The RL circuit shown in figure below is excited at t=0 by a narrow voltage pulse whose magnitude is 1000V and whose width is 10ms.
1. Using Laplace transformation find out the exact current response I (t).
2. Justify using the impulse approximation and solve for the current response due to an impulse approximation of the excitation. And compare the two results.

Answer 1

I don't know..... sorry
