Electric Potential and Capacitance
Capacitor A capacitor consists of two metal electrodes which can be given equal and opposite charges. If the electrodes have charges Q and – Q, then there is an electric field between them which originates on Q and terminates on – Q.There is a potential difference between the electrodes which is proportional to Q. Q = CΔV The capacitance is a measure of the capacity …

$begingroup$ Since the circuit is at a constant potential difference and the pulling apart of the capacitor plates reduces the capacitance,the energy stored in the capacitor also decreases. The energy lost by the capacitor is given to the battery (in effect, it goes to re-charging the battery). Likewise, the work done in pulling the plates apart is also given to the …
Why does the distance between the plates of a …
As Capacitance C = q/V, C varies with q if V remains the same (connected to a fixed potential elec source). So, with decreased distance q increases, and so C increases. Remember, that for any parallel plate …

However, as the distance from the charge to the oppositely charged plate decreases, the potential difference also decreases. This explains why force remains constant, as electric field strength is voltage divided by distance. But why does potential difference decrease if separation of a charge and the plate decrease?
What happens to the electric field and the potential difference …
The electric field between parallel plates depends only on the surface charge density on the plates. Thus if you increase the distance between the plates, the electric field remains constant assuming you are not fixing the potential difference between them. $endgroup$ –
