This physics video tutorial explains how to calculate the magnitude of the electric dipole moment and its direction. An electric dipole is simply the combination of a positive charge and a negative charge that have the same magnitude but opposite signs. This video shows you how to calculate the forces exerted on a dipole, the rotational torque acting on it, the potential energy due to its rotation in an electric field, and the work required to rotate it from one angular position to another. This video involves some knowledge of calculus and integration of trigonometric functions such as sine and cosine. This video contains a few practice problems and examples.
