1. Substation 2A have a busbar made of aluminum with a length of 5 meters and a cross sectional area is 4x3 sq. cm. The resistivity of the Aluminum at 20 DegC is 2.82x10^-8 ohm-m. Determine the resistance of the busbar. 2. The resistance of a copper wire at 20 deg.C is 30 ohms. If the temperature coefficient of copper at 0 deg.C is 0.00427, what is the resistance if the temperature is increased by 30 degrees?
