The step response is the response of the circuit due to a sudden application of a DC voltage or current source.
The step response of a circuit is its behavior when the excitation is the step function, which may be a voltage or a current source.

Step Response of an RL Circuit
To find the step response of an RL circuit, the following is required:
When the DC source of an RL circuit is suddenly applied, the voltage or current source can be modeled as a step function, and the response is known as a step response.
