Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q. …

electrostatics
If your capacitor starts out uncharged, then unless you add or remove charge to it, it will always remain net neutral. Charging a capacitor simply applies a voltage to both sides (i.e. it doesn''t add or remove charge), so the capacitor must remain net neutral. In other words, the two plates must store equal amounts of charge.
Capacitors in Series and Series Capacitor Circuits
Therefore each capacitor will store the same amount of electrical charge, Q on its plates regardless of its capacitance. This is because the charge stored by a plate of any one capacitor must have come from the plate of its adjacent capacitor. Therefore, capacitors connected together in series must have the same charge. Q T = Q 1 = Q 2 = Q 3 ...
electrostatics
If air is the medium between the plates of the parallel plate capacitor, then the electrical field at the position of the grounded plate will be E=σ/2ε; and the electrical field at that place for the grounded plate itself will be E"=0, as for the grounded plate itself there will be equal but opposite amount of field produced. So net will be zero.

$begingroup$ 2)For field lines, it can be proved using gauss law too, consider a surface loop which cover complete circuit, as we know that circuit is neutral, net flux must be zero, and using assumption that wire elements have no capacitance, the net flux coming out from one plate of capacitor must end up at another plate as these two plates are only ones who can hold …

Introduction to Capacitors, Capacitance and Charge
The parallel plate capacitor is the simplest form of capacitor. It can be constructed using two metal or metallised foil plates at a distance parallel to each other, with its capacitance value in Farads, being fixed by the surface area of the conductive plates and the distance of separation between them. Altering any two of these values alters ...

The potential difference across the plates is (Ed), so, as you increase the plate separation, so the potential difference across the plates in increased.

How does charge gather on both plates of the capacitor?
In my textbook, it states that when a parallel-plate capacitor is connected to a battery, charge will flow from the battery onto both plates. How is this possible since current only flows from one end of the battery. Also since the plates are separated the charges don''t flow from one plate to another like they normally would.
What happens when plates of a fully charged capacitor are …
Infinities can be tricky. The force between two charged particles varies inversely with the square of the distance between them. The energy required to increase the distance between two oppositely-charged particles from d 1 to d 2 is the integral of the force over that path. Even if d 2 is infinite, this integral has a finite value.. This result generalizes to large collections …

Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q. V = E x d So, if d (distance) bet plates increases, E (electric field strength) would drecrese and V would remain the ...
