  1. impedance

    Impedance is a measure of the opposition that a circuit or a part of a circuit presents to the flow of electric current. It includes both resistance, which does not change with the frequency of the signal and reactance, which varies with the frequency. It is a complex value usually represented in electrical engineering by the symbol Z and is measured in units of ohms.

The Standard Electrical Dictionary

  1. Impedance

    The ratio of any impressed electro-motive force to the current which it produces in a conductor. For steady currents it is only the resistance. For variable currents it may include besides resistance inductance and permittance. It is the sum of all factors opposing a current, both ohmic and spurious resistances. It is often determined and expressed as ohms. Synonym--Apparent Resistance--Virtual Resistance.
