Energy Density of an Electrostatic Dipole
Energy Density of an Electrostatic Dipole
The positive and negative charges are at . The potential of the dipole in cylindrical coordinates does not depend on because of symmetry. The graphs show the contour plots of the potential or electrostatic energy density in the neighborhood of the charges.
