Consider two wires made of different materials. Wire A has a conductivity of 1.3 × 107 Ω-1m-1, and wire B has a conductivity of 5.1 × 107 Ω-1m-1. Wire A has a circular cross-section with radius 3.78 mm. If there is an electric field of 0.085 V/m inside it, how much current, in amperes, is flowing through it? Wire B has a square 3.78 mm × 3.78 mm cross-section. If wire B has the same electric field as Wire A did in part (a), what current, in amperes, would be passing through it?
