Capacitors are "containers for storing charges". Although there are many kinds of capacitors, their basic structure and principle are the same. A capacitor is formed by a material (solid, gas, or liquid) separating between two pieces of metal that are very close to each other. Two pieces of metal are called polar plates, and the middle material is called a medium. Capacitors are also divided into fixed capacity and variable capacity. But the common capacitance is fixed capacity, the most common is electrolytic capacitance and ceramic chip capacitance.
The ability of different capacitors to store charges varies. The amount of charge stored when a capacitor is added to a 1 volt DC voltage is defined as the capacitance of the capacitor. The basic unit of capacitance is the Farragon F). But in fact, Farah is a very rare unit, because the capacity of a capacitor is often much smaller than that of a farah. It is commonly used in micrometers (μ F), nanofiltration (nafa), pictophoresis (pico), and so on. The relationship between them is: 1 Faradin = 1000000 micrometer (μ F) 1 micromethod (μ F = 1000 nafa n FU = 1000000 piperofaphane).
