Problem 2: Moving around circuits A series circuit consisting of three batteries and a single resister is shown at right. We pick the reference point of the potential at point a (so Va = O V). A. Determine the potentials at points 19 through f. B. Complete the graph of potential vs. location on the circuit. Label important values on the vertical axis. V locations Another circuit is shown below with three equal resistors and only one battery. C. The reference point ofthe potential is again at point a (so Va = O V). Determine the potential at each of the other marked points. D. Use your answers to ll out the graph of potential vs. position around the circuit below. locations
