Wires A and B, having equal lengths of 40.9 m and equal diameters of 2.65 mm, are connected in series. A potential difference of 63.0 V is applied between the ends of the composite wire. The resistances are RA = 0.125 Ω and RB = 0.718 Ω. For wire A, what are (a) magnitude J of the current density and (b) potential difference V? (c) Of what type material is wire A made (see the table below)? For wire B, what are (d) J and (e) V? (f) Of what type material is B made?
