The Parallel Plate Capacitor
We divide the regions around the parallel plate capacitor into three parts, with region 1 being the area left to the first plate, region 2 being the area between the two plates and region 3 being the area to the right of plate 2. Let us calculate the electric field in the region around a parallel plate capacitor.
8.4: Energy Stored in a Capacitor
A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. To gain insight into how this energy may be expressed (in terms of Q and V ...

18.4: Capacitors and Dielectrics
The most common capacitor is known as a parallel-plate capacitor which involves two separate conductor plates separated from one another by a dielectric. Capacitance (C) can be calculated as a function of charge an object can store (q) and potential difference (V) between the two plates:
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.

Capacitor Voltage Current Capacitance Formula – What is Capacitor
Capacitance is the ratio of the charge on one plate of a capacitor to the voltage difference between the two plates, measured in farads (F). Note from Equation.(1) that 1 farad = 1 coulomb/volt. Although the capacitance C of a capacitor is the ratio of the charge q per plate to the applied voltage v, it does not depend on q or v .

8.2: Capacitance and Capacitors
The current through a capacitor is equal to the capacitance times the rate of change of the capacitor voltage with respect to time (i.e., its slope). That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open.
