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 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.
When the supercapacitor(for example, but analogues to the rest) discharges, there is a negative ion that is unpaired with a +Q charge, and the repulsive force from the adjacent negative ion causes that unpaird negative ion to float away from the current collector plate to the electrolytic solution.
Every time I look at diagrams of charged capacitors, I can't help but notice two electrostatic forces acting at the same time.
