What is the application of diodes in circuits?

Diode is a kind of asymmetrical electronic component, that is, it only allows one direction to flow, so this kind of unidirectional conductivity is used in rectifier circuit. The measurement is also very simple, that is, it can be directly measured through the resistance file of the multimeter. Because if there is data displayed in one of the two measurements, it means it is normal. If there is no numerical display in the two repeated measurements, it means it has been broken. If it is a light-emitting diode, it will emit light by measuring the diode, so it is more direct.

Diodes are used in many circuits, so according to its characteristics, it will play its unique role in many circuits. For example, a rectifier circuit. After the AC power is transmitted through a transformer, there are 4 rectifier diodes to form a rectifier circuit, which can be converted into DC power through a resistor step-down. Such a rectifier circuit is still used in many circuits. Then these organs can also form a voltage stabilizing circuit, that is, when they are used, they can be connected in series to form a voltage stabilizing effect, and can continuously adjust the voltage to stabilize the voltage.

Diodes are also very effective when used in various household appliances. For example, if this kind of diode is in the power plug, as long as there is electricity, the diode will naturally emit light. If there is no electricity, the diode will not emit light and can act as an indicator light. One of the effects, the effect is still very good. In addition, this kind of diode can also be used as an electronic doorbell, and it can have a good effect through low-voltage power supply. In daily use, our demand for fluorescent lamps is still relatively large, but it is not easy to start fluorescent lamps. At this time, if you use diodes, it will not only be more convenient when starting at low temperatures, but also can quickly start to light up even in winter. The effect is really good. This kind of diode can be used in the circuit of the white woven lamp to better stabilize the voltage and extend the life of the bulb.
