Furnace, Electric. A furnace in which the heat is produced by the electric arc. It is the hottest furnace known to man, and temperatures as high as 7500° Fahrenheit have been developed in it.
Fuse, Electric. A fuse for igniting an explosive charge by electricity. It is made by bringing the terminals or ends of wires close together, so that they will spark when a current passes through them. Or a thin piece of highly resistant wire may be imbedded in an explosive and brought to white heat by current.
Fuse-block. An insulator having a safety-fuse made fast to it.
Fuse-box. A box containing a safety-fuse, generally of porcelain, enamelled iron, or some other non-conductor.
Fuse-links. Links composed of strips or plates of fusible metal serving the purpose of safety-fuses.
Fusing-current. A current of sufficient strength to cause the blowing or fusing of a metal.

Galvanic. Voltaic. Relating to current electricity or the electro-chemical relations of metals.
Galvanic Taste. A salty taste in the mouth resulting from the passage of a light current from a voltaic battery, the ends of the wires being held to either side of the tongue. This has been called tasting electricity, but it is really the decomposition of saliva on the surface of the tongue, due to electrolysis or the passage of a current through a liquid.
Galvanism. The science of voltaic, or current, electricity.
