Inductance in- d9k-t9n(t)s (1886) n. The change in magnetic field due to the variation of a current in a conducting circuit causing an induced counter electromotive force in the circuit itself. The phenomenon is known as self-induction. If an electromotive force is induced in a neighboring circuit the term mutual injection is used. 

Counter-electromotive force The effective electromotive force within a system that opposes the passage... 

When a current is passed through a crystal, the resistance in the low-temperature structure-sensitive conductivity region rises rapidly, as a counter-electromotive force is set up. This... 

Counter Electromotive Force A voltage of an electrochemical cell opposite to the applied external voltage. Also referred to as back EMF. 

Inductance tin-ldok-ton(t)s n (1886) The change in magnetic field due to the variation of a current in a conducting circuit causing an induced counter electromotive force in the circuit itself. The phenomenon is known as self-induction. If an electromotive force is induced in a neighboring circuit the term mutual injection is used. Inductance may thus be distinguished as self- or mutual and is measured by the electromotive force produced in a conductor by unit rate of variation of the current. Units of inductance are the centimeter (absolute electromagnetic) and the Henry, which is equal to 10 cm of inductance. The Henry is that inductance in which an induced electromotive force of... 

An equilibrium electrochemical cell is at the state between an electrolytic cell and a galvanic cell. The tendency of a spontaneous reaction to push a current through the eternal circuit is exactly balanced by an external voltage that is called a counter electromotive force or counter e.m.f. so that no current flows. If this counter voltage is increased the cell becomes an electrolytic cell and if it is decreased the cell becomes a galvanic cell. 

Counter electromotive force A voltage opposite to the applied voltage, also referred to as back e.m.f.
