Electrostatics and Capacitance

For an electrical event to occur you must have two things:

• An electro-static field to provide the potential, and,
• A magnetic field to provide the boundary condition.

Energy must be motivated to travel (the electrostatic) and contained in a tunnel (the magnetic) or no electrical event will occur.

The magnetic field typically breaks down before the electrostatic one does when travelling long distances.
