Circular mil area of conductor
WebA wooden dowel has a diameter of 1.20 \mathrm {~cm} 1.20 cm. It floats in water with 0.400 \mathrm {~cm} 0.400 cm of its diameter above water . Determine the density of the dowel. Verified answer engineering The viscosity of liquids can be measured through the use of a rotating cylinder viscometer. WebThe correct answer is: 500 mils = circular mil area → VII., 10 mils = circular mil area → II., 0.1020 inch = circular mil area → V. To find the approximate resistance of a given copper conductor, drop the ? digit from the circular mil area. The result is the number of ? per ohm. last / feet
