Understanding Step Response in Circuits

The video tutorial explains how to solve a non-homogeneous differential equation for a circuit by analyzing both the natural and forced responses. It begins with setting up the initial conditions and suppressing the voltage source for the natural response. The forced response is then determined by setting initial conditions to zero and using the input voltage. Finally, the total response is obtained by combining the natural and forced responses using the principle of superposition.
