Resumen
The total electrostatic potential energy stored in a system of point charges is conventionally determined by assuming that the least-energy, or electrostatic, configuration is known beforehand. The conventional charge assembly process involves displacing charges from an infinite location to their final resting points and merely summing all interaction energy terms. This process is physically unrealistic because charges already in a system are not displaced by each new charge. Instead, final locations of charges must be obtained as each new charge arrives by minimizing the total energy of the system or equivalently by determining when the net forces on all charges vanish. Here, the objective is to present energy minimization strategies accessible to introductory non-calculus science students
