The standard system used for designating wire diameter. The lower the AWG number, the larger the diameter. Also called the Brown and Sharpe (B&S) Wire Gauge.

Ampacity

See Current-Carrying Capacity.

Ampere

The unit of current. One ampere is the current flowing through one ohm of resistance at one volt potential.

Ampere’s Law

The magnetic intensity at any point near a current-carrying conductor can be computed on the assumption that each infinitesimal length of the conductor produces at the point of an infinitesimal magnetic density. The resulting magnetic intensity at the point is the vector sum of the contributions of all the elements of the conductor.

Analog
