What is the cross-sectional area of 1.4-diameter enameled wire? What is the safe current and the maximum current that can pass through?
1.4/2 = 0.7 0.7 square / 3.14 results find out by yourself
Find 2.5x10 flat line cross-sectional area, and the number of squares! And detailed cross-sectional area calculation formula and the number of squares calculation formula!
Does flat line refer to flat steel? The cross-sectional area will soon be 2.5 * 10 = 25. The cross-sectional area depends on what line you use. Circular line π R ^ 2, rectangle a * B
