Parallel-Plate Capacitor. The parallel-plate capacitor (Figure \(\PageIndex{4}\)) has two identical conducting plates, each having a surface area \(A\), separated by a distance \(d\). When a voltage \(V\) is applied to the capacitor, it stores a charge \(Q\), as shown.
18 Ιουν 2023 · A parallel plate capacitor is defined as an arrangement of two metal plates of equal area A and opposite charge Q, separated by a distance d. The plates are connected to a voltage source V, which creates an electric potential difference between them.
The capacitance of a parallel plate capacitor in equation form is given by \[C=\varepsilon _{0} \dfrac{A}{d}.\] \(A\) is the area of one plate in square meters, and \(d\) is the distance between the plates in meters.
This formula tells us that the capacitance of a Parallel Plate Capacitor depends directly on the area of the plates and inversely on the distance between them. It also shows the role of the permittivity of free space in determining how much charge can be stored for a given voltage.
