reciprocal impedance
1impedance — [im pēd′ ns] n. [< IMPED(E) + ANCE] 1. the total opposition offered by an electric circuit to the flow of an alternating current of a single frequency: it is a combination of resistance and reactance and is measured in ohms: the reciprocal of… …
2Impedance 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… …
3Electrical impedance — Electromagnetism Electricity · …
4Image impedance — is a concept used in electronic network design and analysis and most especially in filter design. The term image impedance applies to the impedance seen looking in to the ports of a network. Usually a two port network is implied but the concept… …
5Mechanical impedance — is a measure of how much a structure resists motion when subjected to a given force. It relates forces with velocities acting on a mechanical system. The mechanical impedance of a point on a structure is the ratio of the force applied at a point… …
6Dual impedance — and dual network are terms used in electronic network analysis. The dual of an impedance is its algebraic inverse . Note that and are the duals of each other, that is, they are reciprocal. For this reason the dual impedance is also called the… …
7electrical impedance — Opposition that a circuit presents to electric current. It includes both resistance and reactance. Resistance arises from collisions of the current carrying charged particles with the internal structure of the conductor. Reactance is an… …
8Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… …
