2. (1) Imagine a single-loop circuit with a battery, two wires, and a 10 Ohm resistor. The wires are also ohmic, but with a resistance much smaller (not ignorable) than the 10 Ohm resistor. Consider all circuit elements except for the battery, and answer the following questions: a. (0.5) Is any physical quantity among current, potential difference, and resistance the same for all these circuit elements? Explain why. b. (0.5) Using Ohm's law, describe how these physical quantities of these circuit elements would relate to each other.
