Cross Sectional Area Of Wire: Formula & Calculation

Web82.20 mils A 2,583-circular-mil cable is composed of 25 strands of copper wire of equal size. What is the approximate diameter of one strand? Round the answer to the nearest tenth. 10.2 mils A 24-ohm resister has a current of 0.65 amperes flowing through it. How much power (watts) is being produced by the resistor? WebNov 15, 2016 · How to find the cross sectional area of a wire First, we define that the diameter of our wire is taken in thousandths of an inch where one one-thousandth of an inch is called “one mil.” Thus, 0.001 inch = 1 … the hub anzac square brisbane

AWG - American Wire Gauge vs. Circular Mils

WebLooking at our wire size table, we find that 14 gauge wire has a cross-sectional area of 4,107 circular mils. If we’re still using copper as a wire material (a good choice, unless we’re really rich and can afford 4600 feet … WebDefinition: One circular mil (CM) is the area of a circle 1 mil in diameter. Figure 1: A circle with the diameter of one mil.
