ls, multiply the area incircular mils by .7854 and the resultis the area in square mils. Or, tochange from square to circular mils, divide the area in squaremils by .7854 and the quotient thus obtained will be the areain circular mils. Example.—The diameter of a circular copper conductoris 102.0… … Fig. 5 Circular-mil area == d2 = (102.0)2 == 10 404 Ans. 10 404 circular mils. (2) The area of a circle in square measure is equal to.7854 times the diameter of the circular squared, or Square mil area = .7854 X d^ = .7854 X (102.0)^ = 8171.3 Ans. 8171.3 square mils. 40. Calculation of Resistance…
