A transient response represents the circuit behaviour once switched on or off. Once a circuit is powered on an electromagnetic wave will traverse through the circuit causing the electrons to move through the circuit with voltages and currents ramping up throughout the circuit before reaching a steady-state.
A circuit response consists of two phases, a transient phase and a steady-state phase, the transient phase occurs when the circuit has been switched on or off and after some time the circuit settles to a steady-state where the voltages and currents in the circuit settle.
A transient voltage is this sudden change in DC voltage when a circuit is switched on/off. we will now learn about transient circuits as well as loads other than resistors.
A typical transient response is shown below where the voltage ramps up exponentially before asymptoting to a steady state value of 5V:
