![]() ![]() If the wire length is longer then it creates high resistance. If the wire length is shorter, then it will make less resistance. With greater resistance, this diminishes current capacity. So this will create heat & friction to form resistance. If the wire size and distance are longer, then more electrons hit each other & the walls of the wire. It is a measure of the wire’s resistance, used to determine the resistance of a wire. ![]() So it will be used if the number of feet of the wire required is known. The wire weight can be determined through a god measure like feet per pound. Meanwhile, AWG 40 wire is the smallest wire, so it uses 34,364 feet of wire to 1lb weight. For instance, AWG 4 wire is the biggest wire, thus it uses simply 7.918 feet of wire to 1lb weight. of feet that a gauge will give you for each 1lb of weight. The CM area of a wire is the square of the MIL diameter.Ī foot for every pound is the no. ![]() A circular mil is a unit of area equal to that of a 1-mil-diameter circle. The area is specified in CM, circular MIL. This is calculated by the typical area of a circle, A=πr2. The area of a wire is an area of its cross-section. Here, 1 mil is equivalent to 0.0254 mm or 0.001 inches. The diameter of the wire can be expressed in different ways like inches, MILs, millimeters. The highest size of wire is if an AWG size is 4 whereas the smallest size of wire is if AWG size is 40. The diameter is twice the radius length of a wire’s circle diameter. In the following gauge chart, there are 40 different gauge sizes available with diameter, area, feet per pound bare, Ohms per 1000ft 25☌, and current capacity in Amps. So commonly used some of the AWG gauge sizes include the following. The standard AWG gauge sizes are available based on the quantity of currency you require for a particular application.
