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.
When a capacitor is connected across a source it observed electrical energy and store it in the form of electrostatic energy. This is because of the accumulation of positive ions on the plates connected to the positive side of the source and negative ions on the side of the capacitor connected to negative side of the source.
