Capacitors store electrical energy in an electric field, created by two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric charge accumulates, allowing the capacitor to store energy. The amount of charge a capacitor can hold is measured in farads (F), with most capacitors used in practical applications measured in microfarads (µF) or picofarads (pF).
B. Types of Dielectric Materials
The dielectric material used in a capacitor significantly influences its performance, stability, and application. Common dielectric materials include ceramic, plastic, electrolytic, and tantalum, each offering unique properties that make them suitable for specific applications. The choice of dielectric affects factors such as temperature stability, voltage rating, and capacitance value.
