To suffer to pass through; as, glass transmits light; metals transmit, or conduct, electricity.

An electric glow lamp having filaments of metallic tungsten. Such lamps, owing to the refractory nature of the metal, may be maintained at a very high temperature and require an expenditure of only about 1.25 watts per candle power.

An electric generator or dynamo which is combined on one frame with a turbomotor, by which it is driven.

To make acid or sour; to ferment; to curdle, etc.: as, to turn cider or wine; electricity turns milk quickly.

of individuality. -- Unit jar (Elec.), a small, insulated Leyden jar, placed between the electrical machine and a larger jar or battery, so as to announce, by its repeated discharges, the amount of electricity passed into the larger jar. -- Unit of heat (Physics), a determinate quantity of heat adopted as a unit of m…

s.), a glass tube provided with platinum electrodes and exhausted, for the passage of the electrical discharge; a Geissler tube. -- Vacuum valve, a safety valve opening inward to admit air to a vessel in which the pressure is less than that of the atmosphere, in order to prevent collapse. -- Torricellian vacuum. See…

A trembler, as of an electric bell. (2)

Containing or exhibiting positive, or vitreous, electricity.

Of or pertaining to glass; derived from glass; as, vitreous electricity. Vitreous body (Anat.), the vitreous humor. See the Note under Eye. -- Vitreous electricity (Elec.), the kind of electricity excited by rubbing glass with certain substances, as silk; positive electricity; -- opposed to resinous, or negative, elec…

A kind of glass which is very hard and difficult to fuse, used as an insulator in electrical lamps and other apparatus.

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

A unit of electric measurement equal to the product of a volt and an ampere. For direct current it is a measure of power and is the same as a watt; for alternating current it is a measure of apparent power.

An instrument for the exact measurement of electric currents.

Electric potential or potential difference, expressed in volts.

Of or pertaining to Alessandro Volta, who first devised apparatus for developing electric currents by chemical action, and established this branch of electric science; discovered by Volta; as, voltaic electricity.

That form of electricity which is developed by the chemical action between metals and different liquids; voltaic electricity; also, the science which treats of this form of electricity; -- called also galvanism, from Galvani, on account of his experiments showing the remarkable influence of this agent on animals.…

An instrument for measuring the voltaic electricity passing through it, by its effect in decomposing water or some other chemical compound acting as an electrolyte.

rument for measuring in volts the differences of potential between different points of an electrical circuit.

An instrument for measuring power in watts, -- much used in measuring the energy of an electric current.

The standard unit of electrical quantity, and also of current. See Coulomb, and Amp. [Obs.]
