what is the work of second plate in parallel capicitter
Answers
Answer:
A parallel plate capacitor consists of two large plane parallel conducting metal plates separated by a small distance. The second plate acts as a neighbouring conductor due to which the potential of first plate is reduced, keeping its size same ;due to which the capacitance increases
Answer:
Parallel Plate Capacitors are the type of capacitors which that have an arrangement of electrodes and insulating material (dielectric). The two conducting plates act as electrodes. There is a dielectric between them. This acts as a separator for the plates.
The two plates of the parallel plate capacitor are of equal dimensions. They are connected to the power supply. The plate, connected to the positive terminal of the battery, acquires a positive charge. On the other hand, the plate, connected to the negative terminal of battery acquires a negative charge. Due to the attraction charges are in a way trapped within the plates of the capacitor.
The Principle of Parallel Plate Capacitor
We know that we can give a certain amount of charge to a plate. If we supply more charge, the potential increases and it could lead to a leakage in the charge. If we get another plate and place it next to this positively charged plate, then negative charge flows towards the side of this plate which is closer to the positively charged plate.
As both the plates have charges, the negative charge on plate 2 will reduce the potential difference on plate 1. On the other hand, the positive charge on plate 2 will increase the potential difference in plate 1. But the negative charge on plate 2 will have more impact. So, more charge can be given on plate 1. Because of the negative charges on plate 2 the potential difference will be less. This is the principle of the parallel plate capacitor.
