During a charged state of a capacitor (Regardless of the type of capacitor),
- Simple parallel plate:
- Parallel plate with dielectric material in the gap:
How is the attractive force between the positive and negative charges much stronger than the repulsive forces between them when accumulated in a certain component(plate,dielectric,double layer)?
When I look at the diagram's above, it seems like there are two forces acting simultaneously, the attractive forces holding the electric field, and the repulsive force between like charges within a component.
When a simple parallel plate capacitor is being charged, all what remains is an accumlation of like-charges in a certain region, I'm curious how they are free to move(when discharging) and stay static in position(when charged and unconnected to a load) while there is a repulsive electrostatic force between like charges.
Every time I look at diagrams of charged capacitors, I can't help but notice two electrostatic forces acting at the same time. Yet, the attractive electrostatic force is relevant all the the modes of analysis(electric field,energy storage, charging/discharging).
