Definition of Impedances

Impedance
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 rootR^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.
