Wires 1 and 2 are identical except that they are each made of a different material. The one end of wire 1 is connected to one end of wire 2. The two remaining ends are connected across a battery and current flows through the two wires. Is the potential difference is wires 1 and 2 the same or different? Is the current in wires 1 or 2 the same or different?
2. Relevant equations
3. The attempt at a solution
The resistivity would change because the material changes; therefore, the resistance changes. If the resistance changes, the current changes. Potential difference remains the same. Is this correct?
