ing to produce, electricity or an electric current; causing electrical action or effects. Electro-motive force (Physics), the force which produces, or tends to produce, electricity, or an electric current; sometimes used to express the degree of electrification as equivalent to potential, or more properly difference of…

An instrument for regulating the electro-motive force in an alternating-current circuit; -- so called because used to "boost", or raise, the pressure in the circuit.

s. It is the quantity of electricity conveyed in one second by the current produced by an electro-motive force of one volt acting in a circuit having a resistance of one ohm, or the quantitty transferred by one ampère in one second. Formerly called weber.

An abbreviation for electro-motive force.

standard unit of electrical capacity; the capacity of a condenser whose charge, having an electro-motive force of one volt, is equal to the amount of electricity which, with the same electromotive force, passes through one ohm in one second; the capacity, which, charged with one coulomb, gives an electro-motive force o…

The unit of electric induction; the induction in a circuit when the electro-motive force induced in this circuit is one volt, while the inducing current varies at the rate of one ampère a second.

One of the larger measures of electro-motive force, amounting to one million volts.

A measure of electro-motive force; the millionth part of one volt.

t that the strength or intensity of an electrical current is directly proportional to the electro-motive force, and inversely proportional to the resistance of the circuit.

hydrogen, and results in an increase of the resistance, and the setting up of an opposing electro-motive force, both of which tend materially to weaken the current of the battery, or that passing through the cell.

s; multiphase; as, a polyphase machine, a machine producing two or more pressure waves of electro-motive force, differing in phase; a polyphase current.

hence, the degree of electrification as referred to some standard, as that of the earth; electro-motive force.

An instrument for measuring or comparing electrial potentials or electro-motive forces.

s measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.

The unit of electro-motive force; -- defined by the International Electrical Congress in 1893 and by United States Statute as, that electro-motive force which steadily applied to a conductor whose resistance is one ohm will produce a current of one ampère. It is practically equivalent to
