Capacitors are electronic components that store energy in an electric field. They are essential elements of electronic circuits that filter, stabilize, and store electrical energy. There are two main types of capacitors: polarized and non-polarized. The main difference between these two types of capacitors is how they store and release electrical charge.
| S.No | Polarized Capacitor | Non-Polarized Capacitor |
|---|---|---|
| 1. | Polarized Capacitors have a positive and negative terminal, which means they must be connected in a specific way in a circuit to work correctly. | Non-Polarized Capacitors do not have a positive or negative terminal, and also can be connected in any orientation in a circuit. |
| 2. | Polarized Capacitors are also called electrolytic capacitors because they use an electrolyte as the dielectric material. | Non-Polarized Capacitors use a variety of dielectric materials, such as ceramic, mica, or film, to store electrical charge. |
| 3. | Polarized Capacitors are commonly used in circuits that require high capacitance values and low cost | Non-Polarized Capacitors commonly used in circuits that require low capacitance values and high precision |
| 4. | Polarized Capacitors are commonly used in power supplies, audio amplifiers, and electronic equipment. | Non-Polarized Capacitors are commonly used in radio frequency filters, timing circuits, and oscillators. |
| 5. | Polarized Capacitors have a larger physical size b/c they require a larger area to accommodate the electrolyte | Non-Polarized Capacitors can use thinner dielectric materials to achieve the same capacitance value. |
