RC Circuit with Source

When a DC source is abruptly applied to an RC (Resistor-Capacitor) circuit, the voltage can be represented as a unit step function. The voltage across the capacitor, known as the step response, characterizes how the circuit reacts to this sudden change in input.

Due to the inherent properties of a capacitor, its voltage cannot change inst...

When a DC source is applied abruptly to an RC circuit, its voltage is represented as a unit step function.

The voltage across the capacitor is the step response.

Since the voltage across a capacitor cannot change instantaneously, its value immediately after switching remains the same as the value immediately before switchi...
