what is the principle of parallel plate capacitor and explain its working with example ?

Principle of Parallel Plate Capacitor

As we know that certain amount of charge can be given to a plate as if more charge is applied its potential will increase and charge might leak.

If we get another plate and place it next to this positively charged plate then negative charge will be pulled towards the side of this plate which is closer to the positively charged plate and positive charge on the further side.

Fig. 1: Two plates of parallel plate capacitor

As both the plates have charges the negative charge on plate 2 will reduce the potential difference on plate 1 while the positive charge on plate 2 will increase the potential difference on plate 1. But the negative charge on plate 2 will have more impact.so more charge can be given on plate 1 because of negative charges on plate 2 the potential difference will be less.
