The impedance of electric circuit refers to the measure of the opposition that a circuit presents to a current when a voltage is applied.
The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
Max power transfer takes place when the total load impedance is equal to the source (power supply) internal impedance.

The impedance of an electric circuit is the measure of the opposition presented by a circuit when the current and voltage is applied.
look at this web page, it is simple. http://hyperphysics.phy-astr.gsu.edu/Hbase/electric/imped.html
Max power transfer takes place when the total load impedance is equal to the source (power supply) internal impedance.
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".
Voltage, frequency, current, impedance, and what the circuit is supposed to do are all important.
impedance
A parallel resonant circuit has low impedance, when non resonant; however the impedance rises sharply, as the circuit comes to resonance.

AnswerThe unit of measurement for impedance is the ohm.
Impedance Inversion in Microwave circuits can be obtained by utilizing the Short Circuit or Open Circuit Transmission line of proper length.
The inductance of an inductor is the capacity of the inductor to induce electric flux. The capacitance of a capacitor is the capacity of the capacitor to store charges. THE IMPEDANCE OF A CIRCUIT IS THE TOTAL OPPOSITION OFFERED TO THE FLOW OF ELECTRIC CURRENT.
1. The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.AnswerThe impedance of an RLC circuit is the vector sum of the circuit's resistance, inductive reactance, and capacitive reactance -all of which are expressed in ohms. This applies whether the circuit is at resonance or not.
