The principle and calculation formula of capacitor and the conversion of capacitance unit

Principle of capacitor

In production and life practice, scientists have found that when the voltage between two conductors separated by insulation is high, the conductor connected to a high potential can hold positive charges, and the conductor at low potential can hold negative charges. Thus it can be seen that the above conductors and insulation have the ability to hold charge, which is called capacitance. And the whole is called the capacitor.

Calculation formula of capacitance

It has been proved that the situation in which any capacitor holds the charge is similar to the situation in which a basketball holds a gas. The greater the air pressure in the atmosphere of the basketball, the more gas it holds; the greater the voltage the capacitor adds, the more charge it will hold. To measure its capacity to charge, it must be measured at the same voltage. The number of charges that can be charged under the unit voltage is called capacitance. It is expressed in C. The unit Fala:

Calculation formula of capacitance

In the formula q is the amount of charge on the capacitor voltage of the U contained in the home.

The capacity of common capacitors in actual use is indicated when they are manufactured. The number or color ring of capacitor elements contains capacity information. Fala 1 is equal to 1 per Coulomb volts, namely capacitance of the capacitor 1 Fala, in the normal operating range, each additional potential 1 volts can store 1 Coulomb charge.

Capacitance unit conversion

The capacity unit is Fala (represented by the letter F), but in practical applications, Fala is too large. The most often used are micromethod (uF) or skin method (PF).
1F=1000,000微法=106微法（uF）
1F=1000000 micromethod =106 micromethod (uF)
1uF=1000,000皮法=106皮法（PF）
1uF=1000000 skin method =106 skin method (PF)

The size of the capacitor is related to the geometrical size of the capacitor and the properties of the medium. In addition to capacitors, in fact, in practice, electrical equipment, lines and components have natural capacity. Longer cables, such as long lines, have capacitances.
