## Natural response and step response

ok i need some clarification if you have a circuit where a current source is in parallel with an inductor a resistor and a capcitor is this considered a natural response or a step response. I guess i thought a step response is if a switch is switched and a source is added then it is a step response not if it was there the whole time.

 Not sure what a "natural response" is... Perhaps it means the steady-state behavior since "step response" is pretty much what you describe: how the circuit behaves when a sudden change in voltage or current is applied.

Neither. It's just considered a circuit.

If the current source contains a step then there will be a step response. If there are nonzero initial conditions then there will be a natural response.

## Natural response and step response

natural response means the a capacitor/inductor is discharging such that after a long time, the voltage and currents approaches 0

step response is when a source will try to charge the inductors capacitors such that after a long time, the capacitors/inductors connected will be charged. if the capacitors/inductors have high initial voltage/current than what the source has to offer they can discharge until it reaches a steady charged state with a lower voltage/current. please correct me, this is how i understand step and natural response
