V R a O e R3 S Potential (V) 0+ a b C d Position Q/C' for the circuit when the switch is closed a (c) The current in resistor R is I. A student writes the correct equation V = I (resistance of R) + I (resistance of R) long time. The student also draws the graph shown above to represent the potential along the circuit path abcdea with the switch closed. Is the graph above consistent with the equation? Justify your answer. e V(resistance of R) (d) Another student writes the correct equation (sum of the three resistances) V - V(resistance of R) (sum of the three resistances) this equation supports your reasoning in part (b) and explain why the equation does or does not support your reasoning using physics principles. a 2 C for the circuit after the switch is closed a long time. Indicate whether (e) Resistor R2 is now replaced by a second capacitor that also has capacitance C, and the switch is left open for a long time. In terms of V, what is the potential difference across each of the capacitors? Justify your answer.
