Parallel plate capacitor is an electronic component used to store electrical energy in an electric field. It typically consists of two conductive plates, often metal, that are parallel to each other and separated by a small distance. This space between the plates is filled with a non-conductive material called a dielectric, which enhances the capacitor's ability to store charge. When a voltage source is connected across the plates, an electric field forms between them, causing one plate to accumulate a positive charge and the other a negative charge. The amount of charge the capacitor can store at a given voltage is its capacitance, which depends on the area of the plates, the distance between them, and the dielectric material used. Parallel plate capacitors are widely used in various electronic circuits for purposes such as energy storage, filtering, and timing.
