Some airliners use wires of aluminum(resistivity 2.75×10−8 Ω ⋅m2.75×10−8 Ω ⋅m) rather than copper to reduce weight. The potential difference between the ends of an aluminum wire 35.0 m long is 1.45 V when the wire carries current 1.20 A. Find (a) the electric-field magnitude inside the wire, (b) the resistance of the wire, and (c) the cross-sectional area of the wire.
