How can energy be stored in a field?
6. Energy stored in fields = the total energy required to assemble the fields. It takes energy to bring the charges to specific positions to assemble the field, and when you let everything go, the charges will just fly apart. The energy you stored in the field becomes the kinetic energy of the charges once you let them go.
