WORDNET DICTIONARY
Noun impedance has 1 sense
- impedance(n = noun.phenomenon) electric resistance, electrical resistance, ohmic resistance, resistance, resistivity - a material's opposition to the flow of electric current; measured in ohms; Array is a kind of electrical phenomenon
has particulars: ohmage
CIDE DICTIONARY
impedance, n. [Impede + -ance.].
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 R2 + X2 R = ohmic resistance, X = reactance. For an inductive circuit, X = 2, where f = frequency and L = self-inductance; for a circuit with capacity X = 1
, where C = capacity. [Webster 1913 Suppl.]
OXFORD DICTIONARY
impedance, n.
1 Electr. the total effective resistance of an electric circuit etc. to alternating current, arising from ohmic resistance and reactance.
2 an analogous mechanical property.
1 Electr. the total effective resistance of an electric circuit etc. to alternating current, arising from ohmic resistance and reactance.
2 an analogous mechanical property.
Etymology
