Two cylindrical rods, one copper (resistivity 1.72 x 10-8 Q-m) and the other iron (resistivity 9.7 x 10-8 Q-m), are identical in lengths and cross-sectional areas. They are joined end to end to form one long rod. A 12-V battery is connected across the free ends of the copper- iron rod. What is the voltage between the ends of the copper rod?

In a circuit consisting of a 9 V battery, about 20 cm of 12-gauge copper wire, and a 60 W light bulb, which of the following correctly describes the motion of charge in the wire? a. The protons move from their initial position in the wire away from the negative terminal of the battery toward the positive terminal of the battery. It would take a proton a short time to travel between the terminals - only a few microseconds. b. The protons are generated in the battery and then move away from the positive terminal of the battery toward the negative terminal of the battery. It would take a proton a long time to travel between the terminals - at least an hour. c. The free electrons move from their initial position in the wire away from the negative terminal of the battery toward the positive terminal of the battery. It would take a free electron a long time to travel between the terminals - at least an hour.
