Working Principle

A ceramic capacitor is a passive electrical component used to store electrical energy. It works by storing an electrical charge between two conducting surfaces separated by a dielectric material. The dielectric material used in ceramic capacitors is usually a ceramic material such as aluminum oxide, barium titanate, or a mixture of these materials. The two electrodes are usually made of a conductive material such as aluminum or copper. When a voltage is applied across the two electrodes, an electric field is produced, which causes the ions in the ceramic to become polarized. This polarization is what creates and stores the electrical charge.

The charge stored in a ceramic capacitor is affected by a number of factors, including the capacitance value, the dielectric material used, and the working voltage of the capacitor. When selecting a ceramic capacitor, it is important to consider the capacitance value, the working voltage, and the size of the capacitor. Additionally, it is important to select a capacitor with a dielectric material that is well suited for the application.
