WebThe cross-sectional area of the wire has 625 circular mils but only 490.625 square mils. Therefore, a circular mil represents a smaller unit of area than the square mil. ... What is the resistance of 1,000 feet of copper wire having a cross-sectional area of 10,400 circular . mils (No. 10 wire) at a temperature of 20º C? Solution: WebThe "gauge" is related to the diameter of the wire. The AWG standard includes copper, aluminum and other wire materials. Typical household copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire. The Circular Mil - CM - is a unit of area used ...
