It is the complex ratio of the voltage to the AC (alternating current) circuit. It extends the concept of resistance to AC circuits due to magnitude and phase.
Measurement of electrical conductivity by knowing the impedance value.
an ohm meter concerning electrical impedance
In terms of electrical engineering, the term "bridging" refers to connecting a load to two amplifiers. This is done to increase the voltage. It can also refer to the use of an impedance with a low source to power an impedance with a larger load, again to maximise the voltage.
Electrical Flow
AnswerThe unit of measurement for impedance is the ohm.
Impedance in physics is the measure of opposition to the flow of alternating current in an electrical circuit. It includes both resistance and reactance. In electrical circuits, impedance affects the flow of current and voltage, influencing the overall behavior and performance of the circuit.
Impedance is not unique to ham radio and applies to all electronics. Impedance is a property of electrical circuits that can impede the current from flowing.
Impedance phlebography is a noninvasive test that uses electrical monitoring to measure blood flow in veins of the leg.

Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system. Scroll down to related links and look at an example: "Interconnection of two audio units".
The difference between high impedance and low impedance is the amount of resistance in an electrical circuit. High impedance means there is a high level of resistance, which limits the flow of current. Low impedance means there is a low level of resistance, allowing for a greater flow of current.
