Except for resistors Capacitor is the second most commonly used componentThe main physical characteristic of a capacitor is the storage of charge Due to the storage of electric 

charge, it means the storage of energy Therefore, it can also be said that capacitors are energy storage

 components More precisely, it is the storage of electrical energy Two parallel metal plates form a 

capacitor There are also various types of capacitors It includes a fixed capacitor Variable capacitance 

Electrolytic capacitor. Ceramic capacitors Mica capacitors Polyester capacitors Tantalum capacitors, etc 

Tantalum capacitors are particularly stableCapacitors can be divided into fixed capacitors and variable capacitors Fixed capacitors are often used 

as couplings in circuits wave filtering. Points Differential Together with resistors, it forms an RC 

charging and discharging circuit Together with inductors, it forms LC oscillation circuits, etc Variable 

capacitors can be arbitrarily changed in capacity within a certain range So when it forms an LC circuit 

together with an inductor The resonant frequency of the circuit will vary with the capacity of the 

variable capacitor The general receiver circuit uses this principle to change the receiving frequency of 

the receiverThe so-called capacitor It is an electronic component that contains and releases charges The basic 

working principle of a capacitor is charging and dischargingOf course, there is also rectification Oscillatory and other effects In addition, the structure of 

capacitors is very simple Mainly composed of two positive and negative electrodes andComposed of insulating medium sandwiched in the middle So the type of capacitor is mainly 

determined by the electrode and insulating medium Capacitors have many uses There are mainly the 

following types:1. DC blocking: Its function is to prevent DC from passing through and allow AC to pass through2. Bypass (decoupling): Provides a low impedance path for certain parallel components in 

an AC circuit3. Coupling: acting as a connection between two circuits Allow communication signals to 

pass through and be transmitted to the next level circuit4. Filtering: This has a significant impact on DIY And provide compensation Improve the stability 

of the circuit

6. Timing: Use capacitors and resistors in combination Determine the time constant 

of the circuit7. Tuning: Systematically tuning circuits related to frequency For example, a mobile phone radio. 

Television.8. Rectification: Turn on or off semi closed conductor switching elements at predetermined times9. Energy storage: storing electrical energy Used for release when necessary For example, 

camera flash Heating equipment, etc Nowadays, the energy storage level of some capacitors is 

close to that of lithium batteries. One capacitor can store enough electricity to power a mobile

 phone for a day
