    • 2.1: Potential Energy of Charge Assembly
      Charges interact through electric forces, which do work when the charges are moved. Assembling collections of charge therefore results in a potential energy change.
    • 2.2: Electrostatic Potential
      We defined an electric vector field as the force on a charge divided by that charge, so that it depends only on the source charges. We now do the same to define a scalar potential field by dividing the potential energy of a charge by that charge.
    • 2.3: Computing Potential Fields for Known Charge Distributions
      Just as we did for electric fields, we can calculate the potential field of a given charge distribution. While the procedures of these two calculations are similar, there are some important differences.
