To find the capacitance C, we first need to know the electric field between the plates. A real capacitor is finite in size. Thus, the electric field lines at the edge of the plates are not straight lines, and the field is not contained entirely between the plates.
Set the initial separation of the two plates to be 2 mm. It is recommended to adjust and fix the position of the fixed plate such that the movable plate indicator reading on the scaled slide gives the plate separation directly. NOTE: The capacitor plates should be in parallel. If not, please ask your TA or technician for help.
A common form – a parallel plate capacitor – the capacitance is calculated by C = Q / V, where C is the capacitance related by the stored charge Q at a given voltage V. The capacitance (measured in Farads) of a parallel plate capacitor (see Figure 1-1) consists of two conductor plates and is calculated by: Figure 1-1. Parallel Plate Capacitor
This can be seen in the motion of the electric field lines as they move from the edge to the center of the capacitor. As the potential difference between the plates increases, the sphere feels an increasing attraction towards the top plate, indicated by the increasing tension in the field as more field lines "attach" to it.
The surface potential characterises the nature of the charge at the oxide silicon interface. Capacitance of parallel plate capacitor with gap equal to the depletion layer width and dielectric constant for silicon. For the total capacitance C we must add these two capacitances in parallel, ie. ie. This is the maximum capacitance.
The charge, Q, on the plates and the voltage, V, between the plates are related according to the equation where C is the capacitance which depends upon the geometry and dimensions of the capacitor. For a parallel plate capacitor with plate area A and separation d, its capacitance is ε A

Edit: Also, another problem I noticed was that even if we remove the negative plate from the capacitor and then apply Gauss''s Law in the same manner, the field still comes out to be $sigma/epsilon_0$ which is clearly wrong since the …

With the electric field thus weakened, the voltage difference between the two sides of the capacitor is smaller, so it becomes easier to put more charge on the capacitor. Placing a dielectric in a capacitor before charging it therefore allows …
