(a) To introduce an electrostatic charge, as to charge a condenser. (b) To decompose the elements of a secondary battery, q. v., so as to render it capable of producing a current. Thus, a spent battery is charged or recharged to enable it to do more work.

The quantity of electricity that is present on the surface of a body or conductor. If no electricity is supplied, and the conductor is connected to the earth, it is quickly discharged. A charge is measured by the units of quantity, such as the coulomb. The charge that a conductor can retain at a given [...]

Of interest, electrically, as affecting the telephone, they comprise: (1) Pitch, due to frequency of vibrations. (2) Intensity or loudness, due to amplitude of waves of sound. (3) Quality or timbre, the distinguishing characteristics of any specific sound due to overtones, discords, etc., by which the sound is recognizable from others. The telephone is held [...]

A characteristic curve of a shunt dynamo, in which the relations of volts to amperes in the shunt circuit is plotted.

In a dynamo the characteristic curve in which the relations of volts between terminals to amperes in the outer circuit are plotted.

A characteristic curve of a dynamo which indicates a fall in voltage when an excessive current is taken from the dynamo in question. It is shown strongly in some Brush machines, and is partly due to the arrangements for cutting out two of the coils as they approach the neutral line. It is an advantage, [...]

A curve indicating the variations in electro-motive force developed during the rotations of the armature of a dynamo or other generator of E. M. F. The term as used in the electrical sense is thus applied, although the indicator diagram of a steam engine may be termed its characteristic curve, and so in many other [...]

The interior of the bulb of an incandescent lamp.

Abbreviation or symbol for Centimeter-gram-second, as the C. G. S. system.  It is sometimes expressed in capitals, as above, and sometimes in small letters, as the c. g. s. unit of resistance.

The usual type of steam-engine governor. The motion of the engine rotates a system of weights, which are forced outward by centrifugal force, and are drawn inwards by gravity or by springs. Moving outwards they shut off steam, and moving inwards they admit it, thus keeping the engine at approximately a constant speed. The connections [...]
