Consider a wire made of copper with conductivity 6.0 × 107 Ω-1m-1, which has a circular cross-section of radius 0.79 mm. In a particular circuit, this wire carries a current of 4.5 A. a. What is the electric field, in volts per meter, inside this wire? b. If we replace this wire with a gold one of the same size, with conductivity 4.1 × 107 Ω-1m-1, what will the electric field in the wire be
