Tiếng ViệtIn today’s electrical systems and electronic circuits, we often see capacitors equipped with many different purposes depending on the parameters and functions of that capacitor. Capacitors have many different types and parameters and are known with the official parameter as the capacitance, also known as the capacitance of the capacitor, which represents the strength and weakness of the capacitor or represents the ability of the capacitor to charge. capacitor.

The capacitance of a capacitor does not depend on what factors ?
Capacitor is a device in which two conductors are placed close to each other and separated by an insulating layer, each conductor on the capacitor is called a plate of the capacitor. The capacitance of the capacitor TTTT is a quantity that represents the strong and weak parameters of the capacitor’s charge based on the magnitude of the capacitance.
What does the capacitance of a capacitor depend on? Capacitance of a capacitor does not depend on the nature of the two capacitor plates, currently the most commonly used capacitor is a flat capacitor with two flat metal plates placed parallel to each other and separated by a dielectric layer. .
What is the unit of capacitance of a capacitor and the formula for calculating capacitance
What is the unit capacitance of a capacitor?
Capacitance of a capacitor has units of Fara (F) and what is the symbol for capacitance? Capacitance is denoted by C (capacitance), so 1F is the capacitance of a capacitor that when the potential difference between the two plates is 1V, the charge of the capacitor is 1C. In engineering, a capacitor is a place to store energy and provide instantaneous power to use a sharp increase in system voltage based on the F parameter.
Capacitance represents the ability to charge at a certain value of potential difference of the capacitor, When applying a voltage difference U to the two plates of the capacitor, a charge will occur between the two plates, the capacitance will be stored in the capacitor and discharged when needed to increase the voltage in the circuit.
Formula for calculating capacitance
The formula for calculating capacitance is calculated as: capacitance of the capacitor (C) equals the charge of the capacitor (q) divided by the potential difference applied to the two plates of the generator capacitor. This is the most basic formula to calculate the capacitance of a circuit, but there are still specific ways to calculate it based on the type of capacitor such as: Flat capacitor, cylindrical capacitor, crane capacitor.
When connecting multiple capacitors together we can calculate the capacitance as follows:
For capacitors connected in parallel: The total capacitance is equal to the sum of the values of the capacitances connected in parallel.
For series capacitors: The total capacitance is equal to the sum of one over the value of the capacitances connected in series.

How to change the unit of capacitance
Capacitance usually has a unit of F, but when it is manufactured into a capacitor, the unit is uF, so we will change the unit of capacitance as follows:
Capacitance | Converted in |
| 1F | 0,001 kF |
1F | 1 000 mF |
| 1F | 1 000 000 uF |
1F | 1 000 000 000 nF |
| 1F | 1 000 000 000 000 pF |
