Apologies in advance if this question seems trivial, I seem to have missed something conceptually and would like some clarification. If an electric field from a point charge does work on another charge and thereby loses energy, where does the lost energy come from? It is my understanding that the energy in the electric field is directly proportional to the magnitude of the point charge from which it comes. Does this mean when the electric field does work, the point charge effectively loses charge? To me that seems to make no sense, so if anyone could clarify I would appreciate it. Thanks for your time.
