A fundamental fact of electricity is that every proton and electron in an atom have a unique, fascinating trait called an electric charge. This property of protons and electrons to have an electric charge causes mysterious forces to appear between them – the electric forces. Figure 1. Electrostatic lamp. Image courtesy of Niek Verlaan.
