 Coulomb's Law Force: SI units Newtons Electric Field A positive point charge will move in the same direction as the electric field vector. A negative charge will move in the opposite direction. SI units: N/C or V/m Electric Potential Energy (U) The electric potential energy of a charge q at a point in space is the amount of work required to move it from infinity to the point. SI units: Joules Electric Dipoles * p is the dipole moment (p = qd) *the dipole feels no translational force, but experiences torque about the center causing it to rotate, so that the dipole moment aligns with the electric field. Electric Potential The amount of work required to move a positive test charge from infinity to a particular point divided by the test charge. SI units : Volt = J/C Potential Difference (Voltage)  SI units: Volt = J/C Potential Difference (Voltage) when two oppositely charged parallel plates are separated by a distance d, an electric field is created, and a potential difference exists between the plates, given by: V = Ed Authorawc1990 ID227423 Card SetPhysics Quicksheets - Electrostatics DescriptionKaplan Quicksheets Chapter 6 Updated2013-07-17T17:55:55Z Show Answers
