impedance (mass) | impedance

impedance (encz) | impedance,impedance n: Zdeněk Brož |
impedance (czen) | impedance,impedancen: Zdeněk Brož |
Impedance (gcide) | Impedance \Im*ped"ance\, n. [Impede + -ance.] (Elec.)
The apparent resistance in an electric circuit to the flow of
an alternating current, analogous to the actual electrical
resistance to a direct current, being the ratio of
electromotive force to the current. It is equal to root{R^2
+ X^2}, where R = ohmic resistance, X = reactance. For an
inductive circuit, X = 2[pi]fL, where f = frequency and L =
self-inductance; for a circuit with capacity X = 1 [div]
2[pi]fC, where C = capacity.
[Webster 1913 Suppl.] |
impedance (wn) | impedance
n 1: a material's opposition to the flow of electric current;
measured in ohms [syn: electric resistance, {electrical
resistance}, impedance, resistance, resistivity,
ohmic resistance] |
impedance (foldoc) | impedance
Opposition to flow of alternating
current. Impedance consists of resistance plus reactance
(capacitive or inductive). Measured in Ohms.

acoustic impedance (wn) | acoustic impedance

acoustic reactance is the imaginary component [syn:
acoustic resistance, acoustic impedance, {acoustic
