January 29, 2009 PHY 2054 Discussion Spring ‘09 Conceptual Review: Chapter 16 A . Potential Energy & Potential 1. A charge moves along an electric field. Does the potential energy of the charge increase or decrease? 2. A charge q is released from rest and moves along electric field E over a distance of d . What is the change in kinetic energy of the charge? B. Potential due to Point Charges 1. How do you calculate the potential due to multiple point charges? 2. Relate the work required to move a charge to infinity with the initial potential energy of the charge. C. Capacitors 1. Does the potential difference across a capacitor increase or decrease if you increase the plate spacing w/o altering the charge on the plates? 2. Does the charge on a capacitor increase or decrease if you increase the plate spacing w/o altering the potential difference between the plates? D. Combination of Capacitors 1. Two capacitors are connected in parallel/in series. What quantity they have in common? 2. Describe when two capacitors are said to be connected in parallel or series.
