Current Flow In electric current flow, it is found that the resistance offered by a fixed length of wire of a given material varies inversely as the square of the diameter of the wire. If a wire 0.01 in. in diameter has a resistance of...
12) The illumination, I, produced by a light source varies inversely as the square of the distance, D from the light source. Suppose the illumination, I, was 88 footcandles when the distance, D, from the light source was 5 feet. Find the illumination, I, produced when the distance, D, is 4 feet from the same source. Round answer to the nearest tenth of a footcandle. 12) The illumination, I, produced by a light source varies inversely as the square of...
