The total response in an RL circuit to any forcing function will consist of two terms – the transient response (or natural response) and the forced response. The transition from the initial state of the circuit (which is encoded in a single number in the form of an initial inductor current specification at t = 0) to the final state (in which only forced response will be present) is accomplished with the help of the transient response. Now, we introduce a new term called the steady-state response and relate it to the response terms we are already familiar with.

Our study of the solution of differential equation describing the RL circuit has shown us that the total response will always contain two ...
