WebThe general approach to calculate input impedance (or output impedance) is to inject a small current into the input node (di) and look at the resulting change in voltage of the input node (dv). Or, equivalently, to apply a small voltage (dv) and look at the resulting current (di) from your test voltage source. Then compute (dv/di).

WebThe output impedance op-amp is similar to the input impedance. But it refers to how much the source’s apparent voltage changes when it needs to supply more current. For instance, you can spot the current source impedance at work when a battery that isn’t under load has a higher voltage than a battery under load.

Weboutput resistance is much more complex than determining the input resistance.
