Unformatted text preview: at charges will flow from A to B, but I think that must mean the voltage changes. I think that Q = C ΔV means that when Q is reduced, so is ΔV since the capacitance of the capacitor is unchanged. Do you agree or disagree with either or both of these students? Briefly explain your reasoning. d. Let QA be the charge stored on Capacitor A and QB be the charge stored on Capacitor B. Write an equation (using these charges and the capacitances) that utilizes the fact that the voltage drop across each capacitor is the same. e. What is the total charge stored on both capacitors (QA + QB)? f. Solve the above equations for QA and QB. Physics 1B, Winter 2014 Worksheet 2D 3 g. What is the energy stored on each capacitor? h. Using your answer to Question 2.a as a guide, how much energy is lost when the two capacitors are connected and equilibrium is established? 4. The diagram shows three points (A, B and C) in a uniform, ￿ E horizontal electric field with magnitude 1000 V/m. A Points A and B are vertically separated, while points B x and C are horizontally separated. a. Draw at least three equipotential lines. Which line 3 cm xC Bx has the greatest voltage? The least? 4 cm b. What is...
