Impedance is the complex-valued generalization of resistance. It may refer to:
Acoustic impedance, a constant related to the propagation of sound waves in an acoustic mediumElectrical impedance, the ratio of the voltage phasor to the electric current phasor, a measure of the opposition to time-varying electric current in an electric circuitHigh impedance, when only a small amount of current is allowed throughCharacteristic impedance of a transmission lineImpedance (accelerator physics), a characterization of the self interaction of a charged particle beamNominal impedance, approximate designed impedanceImpedance matching, the adjustment of input impedance and output impedanceMechanical impedance, a measure of opposition to motion of a structure subjected to a forceWave impedance, a constant related to electromagnetic wave propagation in a mediumImpedance of free space, a universal constant and the simplest case of a wave impedance referenceEver curious about what that abbreviation stands for? fullforms has got them all listed out for you to explore.
