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?

What is the voltage change if you cross a resistor R in the same direction as the current I? (This means you want Vf-Vi, where Vi is the voltage where the current enters the resistor and Vf, is the voltage where the current leaves the resistor.) What is the voltage change if you cross a resistor R opposite the direction of the current I? (in this case, Vi is the voltage where the current leaves the resistor, and Vf is the voltage where the current enters the resistor.) Which answer is correct? +IR in both cases +IR in the first case and -IR in the second case. +IR in both cases -IR in the first case and +IR in the second case.
