Question

The substation bus bar is made up of made 1.5 inches round copper bars 30 ft long. What is the resistance of each bar?

Answer 1

The substation bus bar is made up of 2-iches round copper bars 20 ft. long. What is the resistance of each bar if resistivity is 1.724 x 10-6 ohm-cm. Determine the resistance of a bus bar made of copper if the length is 10 meters long and the cross-section is a 4 x 4 cm2.
