Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… … Wikipedia
Impedance of free space — The impedance of free space, Z0, is a physical constant relating the magnitudes of the electric and magnetic fields of electromagnetic radiation travelling through free space. That is, Z0 = |E|/|H|, where |E| is the electric field strength and… … Wikipedia

Impedance — is a concept associated with the transmission of waves and electrical signals. There are many kinds of waves, and impedance is different in each of them, hence this disambiguation page. However, impedance is also a unifying concept. It is related … Wikipedia
impedance — 1. Total opposition to flow. In electricity, when flow is steady, i. is simply the resistance, e.g., the driving pressure per unit flow; when flow is changing, i. also includes the factors that oppose changes in flow. Thus, deviations of i., from … Medical dictionary
Characteristic impedance — This article is about impedance in electronics. For impedance of electromagnetic waves, see Wave impedance. For characteristic acoustic impedance, see Acoustic impedance. Schematic representation of a circuit where a source is coupled to a load… … Wikipedia
Nominal impedance — in electrical engineering and audio engineering refers to the approximate designed impedance of an electrical circuit or device. The term is applied in a number of different fields, most often being encountered in respect of: The nominal value of … Wikipedia
