Wires A and B are identical (same length and radius) except that each is made from a different material. The resistivity of wire A is larger than the resistivity of B. One end of wire A is connected to one end of wire B. The two remaining free ends are connected across a battery (so the wires and battery form one continuous loop) and current flows through the two wires. Is the potential difference across the two wires is the same, or is it different? If different, which potential is larger? How about the current through each wire? Are they the same or different, and if different, which current is larger? Please explain your answers. 22
