Overview
What happens when we connect one circuit component to another? Sometimes the circuit component doesn't behave in the same way when it is by itself versus when it is connected to another component. To understand how the circuit will behave, we must consider the input and output impedances of the different parts. The output impedance refers to the impedance, or opposition to current flow, of the component bearing the electrical source. Meanwhile, the input impedance refers to the load component's opposition to current flowing in from the electrical source.
