Passage III

Tables 1 and 2 summarize information about the resistance of some 1-meter (m)-long aluminum and copper wires, respectively, that have different diameters. The resistance of a wire (reported in ohms) restricts the flow of electrons through the wire and results in the.conversion of electrical energy to heat. Table 3 reports the resistance, in ohms, of different lengths of 0.10-mm-diameter aluminum wire at 20°C.

13. To determine if metal type affects resistance, the resistance of a copper wire with a diameter of 0.16 mm at a temperature of 0° C should be compared to the resistance of：

Answer and Explanation

Your Answer is

Correct Answer is A

Explanation

Comparing the resistivity of materials, you should choose different types of materials, but conduct experiments with wires of the same length and the same cross-sectional area at the same temperature
