Chapter 16 Electrical Energy and Capacitance Quick Quizzes 1. (b). The field exerts a force on the electron, causing it to accelerate in the direction opposite to that of the field. In this process, electrical potential energy is converted into kinetic energy of the electron. Note that the electron moves to a region of higher potential, but because the electron has negative charge this corresponds to a decrease in the potential energy of the electron. 2. (b), (d). Charged particles always tend to move toward positions of lower potential energy. The electrical potential energy of a charged particle is PE qV = and, for positively- charged particles, this increases as V increases. For a negatively-charged particle, the potential energy decreases as V increases. Thus, a positively-charged particle located at would move toward the left. A negatively-charged particle would oscillate around which is a position of minimum potential energy for negative charges.
