The simplest form of capacitor diagram can be seen in the above image which is self-explanatory. The shown capacitor has air as a dielectric medium but practically specific insulating material with the ability to maintain the charge on the plates is used. It may be ceramic, paper, polymer, oil, etc.
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
The construction of capacitor is very simple. A capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates are normally made of materials such as aluminum, brass, or copper. The conductive plates of a capacitor is separated by a small distance.
The circuit symbol of a basic capacitor is shown in the below figure. The capacitor symbol is represented by drawing two parallel lines close to each other, but not touching. It consists of two terminals. These terminals are used to connect in the circuit. The ability of a capacitor to store electric charge is called capacitance.
When a DC voltage is placed across a capacitor, the positive (+ve) charge quickly accumulates on one plate while a corresponding and opposite negative (-ve) charge accumulates on the other plate. For every particle of +ve charge that arrives at one plate a charge of the same sign will depart from the -ve plate.
By applying a voltage to a capacitor and measuring the charge on the plates, the ratio of the charge Q to the voltage V will give the capacitance value of the capacitor and is therefore given as: C = Q/V this equation can also be re-arranged to give the familiar formula for the quantity of charge on the plates as: Q = C x V
