In a parallel plate capacitor with air
WebJan 30, 2024 · Two metal plates that are isolated electrically through the air or good insulating material such as ceramic, plastic, mica, etc. are used in a capacitor. It is known as a dielectric for this insulating material. A description of the parallel plate capacitor and its operation is discussed in this article. I. Features 1. Construction WebThe electric field between the plates of parallel plate capacitor is directly proportional to capacitance C of the capacitor. The strength of the electric field is reduced due to the presence of dielectric. If the total charge on the plates is kept constant, then the potential difference is reduced across the capacitor plates.
