Electric Potential of a Point Charge Up to this point we have focused our attention solely to that of a set of parallel plates. But those are not the Example 1: Electric dipole Consider an electric dipole along the y-axis, as shown in the Figure 1.1 below. We would like to derive the electric field at a point P on the x-y plane from the potential V.

Take whatever Q there is, multiply it by the value of the Electric Potential and that tells you how many Joules there would be for the charges in that region, so this Electric Potential energy is between these two charges here, the charge that created the V and the charge that you sticked at that point, and the V is a quick way to figure out how much Potential energy, Electric Potential energy Electric Potential Energy of Three Point Charges #1 Place q1, then q2, then q3, and add all changes in potential energy: U = 0+k q1q2 r12 +k q1q3 r13

Electrostatic Force and Electric Charge Electrostatic Force (charges at rest ): The electric field at the point q due to Q is simply the force per unit positive charge at the point q : E = F/ q E = KQ/r 2 The units of E are Newtons per Coulomb ( units = N/C ). The electric field is a physical object which can carry both momentum and energy. It is the mediator (or carrier) of the electric Electric Potential 53 Picture the Problem The potential at the arbitrary field point P is the sum of the potentials due to the equal but opposite point charges.
