Question: Electrical wire comes in different sizes (different diameters), which are referred to according to their gauge number. For example, a 16-gauge wire has a diameter

Electrical wire comes in different sizes (different diameters), which are referred to according to their “gauge” number. For example, a 16-gauge wire has a diameter of approximately 1.29 mm and is often used for extension cords. Suppose a 9.0-m extension cord composed of 16-gauge copper wire is carry ing 8.0 A of current to a compound miter saw. Determine the voltage drop along the length of the extension cord, remembering that the current must travel down the length of the cord and back.
