EM A model for circuits Part 3: Multiple batteries TellUs On HOOMA HW-26 . Consider the circuit shown at right, which is a variant of circuit IX from the tutorial. All bulbs are identical, and all batteries are ideal and identical. ( of ) N a. Suppose that bulb 1 were unscrewed from its socket. Would C ( of ) the absolute value of the potential difference between points X and Z change?

Two students are asked to rank the electric potentials at points X, Y, and Z in the original (unmodified) circuit. Student 1: "I considered only the right loop. The electric potential at point Z is highest, because it is closest to the positive terminal of battery D. The electric potential O at point y is lowest, because it is closest to the negative terminal of battery D. Point X lies in between. So Vz > Vx > Vy." Student 2: "I considered only the outer loop. Going from point Y to point Z, the electric potential increases by Vo, so AVyz = Vo. Going from point Z to point X, AVzx = Vo So Vx > Vz > Vy." With which student, if either, do you agree? Explain your reasoning. d. Rank the potential differences across batteries C and D (Wbatt c and batt D) and bulbs 1 and 2 (Vbulb 1 and Vbulb 2) according to absolute value, from largest to smallest. If any of these potential differences are either the same or equal to zero, state so explicitly. Explain.
