The regulation of a dynamo so that it shall give a constant current against any resistance in the outer circuits, within practical limits. It is carried out in direct current machines generally by independent regulators embodying a controlling coil with plunger or some equivalent electro-magnetic device inserted in the main circuit and necessarily of low [...]

A term often applied to telegraph recorders, instruments for producing on paper the characters of the Morse or other alphabet.

There are various kinds of electric registers, for registering the movements of watchmen and other service. Contact or press buttons may be distributed through a factory. Each one is connected so that when the circuit is closed thereby a mark is produced by the depression of a pencil upon a sheet or disc of paper [...]

In electro-therapeutics the area or region of the body near the therapeutic electrode.

In electro-therapeutics the area or region of the body remote from the therapeutic electrode.

In electro-therapeutics the restoration of strength or of nerve force by the use of voltaic alternatives, q. v.

Double refraction induced in some materials by the action of either an electrostatic, magnetic or an electro-magnetic field. The intensity or degree of refracting power is proportional to the square of the strength of field.

Treatment of ores by the electric furnace (see Furnace, Electric.) The ore mixed with carbon and flux is melted by the combined arc and incandescent effects of the current and the metal separates. In another type the metal is brought into a fusible compound which is electrolyzed while fused in a crucible. Finally processes in [...]

A resistance coil connected in series with a Voltmeter to diminish the current passing through it. Its resistance being known in terms of the resistance of the voltmeter it increases the range of the instrument so that its readings may cover double or more than double their normal range.

A resistance arranged as a shunt to diminish the total current passing through an ammeter. It is analogous to a galvanometer shunt. (See Multiplying Power of Shunt.)
