A current flow whose direction changes in regular cycles.

The North American standardized wire and cable-sizing system for identifying wire diameter of copper conductors. The higher the gauge number, the smaller the cable.

Also known as "current carrying capacity," it is the capability of handling electric current, as expressed in amperes.

The time it takes for an arc to create a conductive path in a material.

Expressed in decibels (db) per unit length, it is the loss of power in an electrical system.

A covering of one or more wires made from fibrous or metallic filaments that are interwoven in cylindrical form.

The amount of voltage at which the insulation between two conductors or a conductor and ground deteriorates.

The twisting of wires together within the same frequency, in order to achieve a specific gauge.

A term describing the capability of any material to carry an electrical charge, typically expressed in terms of the percentage of conductivity of copper, which has 100% conductivity.

Any material in which electrons can freely move from atom to atom (i.e. electrical current flow). Conductors, which are usually metal, could be a wire that is solid or a stranded multi-wire cable.
