Electrical conductor : ウィキペディア英語版 | Electrical conductor
In physics and electrical engineering, a conductor is an object or type of material that allows the flow of electrical current in one or more directions. A wire is an electrical conductor that can carry electricity along its length. In metals such as copper or aluminum, the mobile charged particles are electrons. Positive charges may also be mobile, such as the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell. Insulators are non-conducting materials with few mobile charges that support only insignificant electric currents. ==Wire size== Wires are conductors that let electricity travel through them to get to a lamp or charger. Wires are measured by their cross sectional area. In many countries, the size is expressed in square millimetres. In North America conductors are measured by American wire gauge for smaller ones, and circular mils for larger ones.
