A. Structure and Components
The structure of a parallel plate capacitor is relatively simple yet effective. It consists of two flat plates, typically made of conductive materials such as aluminum or copper, which are placed parallel to each other. The space between these plates is filled with a dielectric material, which can be air, paper, ceramic, or various polymers. The choice of dielectric material significantly influences the capacitor's performance.
B. Capacitance Formula
The capacitance (C) of a parallel plate capacitor can be calculated using the formula:
\[ C = \frac{\varepsilon A}{d} \]
