Fig. 4.24 shows a series R–L circuit. The circuit is excited RL by an impulse function of magnitude E at time t = 0. Using KVL, we have,
Fig. 4.24 Series RL circuit with impulse input
The Laplace transform of Eq. (4.92) is given below.
If the circuit is initially relaxed i.e, i (0−) = 0, Eq. (4.93) can be written as
The inverse Laplace transform ...
