The definition of high and low potential is based on positive electric charge. The potential at a a is higher than at b b because it takes work by an external agent to move positive charge from the negative plate to the positive plate against the direction of the repulsive force exerted by the electric field E E.
Electrons flow from low to high potential. This is because they have negative charge, so lower potential means higher potential energy. Current is a flow of charge. Let's forgetabout the magnetic field and consider just electrostatics. A particle with charge in an electric field E experiences a force F = E.
If a charge goes from low potential energy to high potential energy, that means the charge is doing work on the electrical field (arguably, in a circuit, charges going from high to low must be balanced by the reverse, but the latter is done by the EMF and is generally omitted from analysis of current flow).
Higher to lower potential or lower to higher to lower potential. Electrons flow from more negative potential to more positive potential because of the way the math was mistakenly set up for electrons to have negative charge. Remember that in a hill problem you could define up to be negative and down to be positive in the coordinates if you wished
Reason: consider one single capacitor not connected to battery, the charge on each plates is zero. Connecting it to a battery (as shown in picture to the right) provides a potential difference which move the charges from on plate to the other: one plate becomes positive +Q1, the other negative -Q2 of equal in magnitude.
The capacitance is an internist propriety of any configuration of two conductors when placed next to each others. The capacitor does not need to be charged (holding a charge Q with a potential difference ΔV across the conductors) for its capacitance to exist: also when a capacitor is not charged it does have a capacitance!
