A Power Center with a power plant of its own supplies a house some distance away with electric power. The house draws 5.0 A of current. This current runs from the power plant along a buried copper wire, during radios in the house, and back to the plant along an equal copper wire. A voltmeter associated across the lines at the plant reads 140 volts. It is then connected across the lines at the house and reads 100 volts. The resistivity of copper is 1.7 x 10 -8 Ω*m, and the cross-sectional area of the copper wire is 2.1 x 10 -6 m 2. Compute the total length of the wire.
