C1. There are two wires, one is made of copper and the other one is silver. These two wires of the same length are made, one from each of the materials. Is it possible for each wire to have the same resistance? a. Yes, because the two wires have the same length. b. Yes, because copper and silver have the different resistivity. c. No, because the two wires have the same length. d. No, because copper and silver have the different resistivity. C2. A flashlight requires two 1.5-volt batteries for it to light.
