2/15/2012 1 PHY132S Introduction to Physics II Class 12 – Outline: Electric Potential Energy Electric Potential: V Voltage: V Announcement I will be out of the office on Thursday and Friday, so I will not have office hours at the usual time. However, I will be accessible by email. Please email me before the Friday deadline if you have questions about test 1. Last Time: the Electric Potential Energy Coulomb s Law for Force Electric field Electric potential energy Voltage Electric potential Last Time: the Electric Potential Energy In a uniform E field (parallel plate capacitor) Two point charges U elec  K Positive charges gain kinetic energy in the direction of E, whereas negative charges gain kinetic energy in the directory opposite E. The potential energy of an electric dipole p in a uniform electric field E is The Potential Energy of a Dipole E ------------------------------------------ +++++++++++++++++++++++++++++++++++++++++++ + - + - The potential energy is minimum at Φ = 0° where the dipole is
