Step Response of RC Circuits

The video tutorial explains the step response of an RC circuit, starting with a brief review of the concept. It then sets up a real example circuit with specific resistor and capacitor values. The RC time constant is calculated, and the step response equation is derived. Finally, the step response is plotted and analyzed, showing the voltage change over time and comparing it to initial sketches.
