Common electronic components What are the common electronic components?

1, resistance

Resistance, due to the blocking effect of substances on current, is called resistive substances under action. Resistance will lead to the change of electron flux. The smaller the resistance, the greater the electron flux, and vice versa. A substance with no or little resistance is called an electrical conductor, or conductor for short. Substances that cannot form current transmission are called electrical insulation and insulators.

2. Capacitance

Capacitance (or capacitance) refers to the amount of charge stored under a given potential difference; C, the international unit is Farah (F). Generally speaking, charges are forced to move in an electric field. When there is a medium between the conductors, the charge will be prevented from moving and accumulating on the conductors. The most common example of charge accumulation is two parallel metal plates. It is also the common name of capacitor.

3. Crystal diode

Semiconductor double-ended devices in crystal diode solid-state electronic devices. The main feature of these devices is nonlinear current-voltage characteristics. Since then, with the development of semiconductor materials and processes, crystal diodes with various structures and different functions have been developed by using different semiconductor materials, doping distributions and geometric structures. Manufacturing materials include germanium, silicon and compound semiconductors.

4. Zener diode

Zener diode (also called Zener diode) is a semiconductor device, and its resistance is always high until it reaches the critical reverse breakdown voltage.
