In electronic components, impedance refers to resistance in the form of a complex number that represents the relationship between voltage and current in an alternating current (AC) circuit. Impedance plays a similar role to resistance in direct current (DC) circuits, but includes the effects of inductance and capacitance as well as resistance.
The Importance of Impedance
Impedance is a very important concept in electronic circuits and plays a key role in many applications:
Signal propagation: Determines the magnitude and phase of signals within a circuit.
Power transfer: For efficient power transfer, the impedance of the load and source must be matched. This is called impedance matching.
Filter design: Impedance is used to design filters that block or pass specific frequency bands.
Resonant circuit: Design a circuit that resonates at a specific frequency using the reactance of inductors and capacitors.
