7.4 The Step-Response
of a RC Circuit (3)
•  Three steps to find out the step response of an RC circuit:
1.The initial capacitor voltage v(0).
2.The final capacitor voltage v(¥) — DC voltage across C.
3.The time constant t.
Note: The above method is a short-cut method. You may also determine the solution by setting up the circuit formula directly using KCL, KVL , ohms law, capacitor and inductor VI laws.
