Electric potential Electric potential is more commonly known as voltage. The potential at a point a distance r from a charge Q is given by: V = k Q / r Potential plays the same role for charge that pressure does for fluids. If there is a pressure difference between two ends of a pipe filled with fluid, the fluid will flow from the high pressure end towards the lower pressure end. Charges respond to differences in potential in a similar way. Electric potential is a measure of the potential energy per unit charge. If you know the potential at a point, and you then place a charge at that point, the potential energy associated with that charge in that potential is simply the charge multiplied by the

Unformatted text preview: potential. Electric potential, like potential energy, is a scalar, not a vector. connection between potential and potential energy: V = PE / q Equipotential lines are connected lines of the same potential. These often appear on field line diagrams. Equipotential lines are always perpendicular to field lines, and therefore perpendicular to the force experienced by a charge in the field. If a charge moves along an equipotential line, no work is done; if a charge moves between equipotential lines, work is done. Field lines and equipotential lines for a point charge, and for a constant field between two charged plates, are shown below:...
