Metallic Conductor. A conductor composed of a metal.
Metallic Filament. A metal wire used in an incandescent lamp—the filament.
Metallic Resistance. (See [Resistance, Metallic].)
Metallurgy. The art of working metals. Electro-metallurgy applies to the processes wherein electricity plays the most important part.
Mica. A natural mineral of sheet form and translucent, used extensively as an insulator in electrical equipment and mechanism.
Mica, Moulded. A composition composed of ground mica and shellac as a binder. When heated and pressed into various shapes and forms, it is a valuable insulator, and is employed for hooks, locks, tubes, sockets, and the like.
Micanite. An insulating material made by cementing laminations of pure mica together and cementing them with shellac or other suitable non-conducting adhesives.
Molecular Adhesion. The attraction of similar molecules for each other.
Molecular Attraction. The attraction of molecules, or physical affinity.
Molecular Resistance. The resistance which a mass or electrolyte offers when contained in an insulated vessel and a current of electricity is passed through it.
