5.15: Changing the Distance Between the Plates of a Capacitor
The potential difference across the plates is (Ed), so, as you increase the plate separation, so the potential difference across the plates in increased. ... That is, the capacitor will discharge (because (dot Q) is negative), and a current (I=frac{epsilon_0AVdot x}{x^2}) will flow counterclockwise in the circuit. (Verify that this ...

Capacitor
One plate of the capacitor holds a positive charge Q, while the other holds a negative charge -Q. The charge Q on the plates is proportional to the potential difference V across the two plates. The capacitance C is the proportional constant, Q = CV, C = Q/V. C depends on the capacitor''s geometry and on the type of dielectric material used.

then why is there no potential difference between the two capacitors. It''s not quite clear what you mean here but do understand that charged capacitors are electrically neutral.. When a capacitor is "charged", it is not electrically charged, it is energy charged in the same sense as when we say a battery is charged.. There is nothing mysterious about two …

18.5: Capacitors
The constant of proportionality, (C), between charge and potential difference across the capacitor (usually called voltage across the capacitor) is called "capacitance", and has S.I. units of "Farads", (F). The capacitance of a particular capacitor is a measure of how much charge it can hold at given voltage and depends on the ...
electrostatics
Equilibrium is reached when the two potentials are equal because, with no potential difference between connected plates of the capacitors, there is no electric field within the connecting wires to move conduction electrons. The initial charge on capacitor 1 is then shared between the two capacitors.
What Is the Potential Difference Across Each Capacitor?
The potential difference in capacitors determines the amount of electric potential energy stored in the capacitor. It represents the work done to move a unit charge from one plate to the other and is measured in volts (V) . In a circuit with capacitors, the potential difference can vary depending on the circuit configuration.
