What is a power relay? The working principle of power relay

A power relay is a device that uses an electromagnet to open or close the circuit when the input (coil) is properly excited. They provide a high level of isolation between the control signal (coil) and the output (contact)-usually the rated pulse voltage is 4 or 6kV.

What is an inductor?

What is an inductor?

Inductors can be said to be the simplest of all electronic components. It is a passive double-ended electronic component that stores energy in a magnetic field when current flows.

What is an oscillator?

What is an oscillator?

Oscillators are mechanical or electronic devices that work according to the principle of oscillation: periodic fluctuations between two objects based on changes in energy. Computers, clocks, watches, radios, and metal detectors are among the many devices that use oscillators.

Transistor replacement principle

Transistor replacement principle

Transistor replacement principles can be summarized into three types: the same type, similar characteristics and similar appearance. One—same type 1. The materials are the same, that is, germanium tubes replace germanium tubes, and silicon tubes replace silicon tubes.

Advantages of transistors

Advantages of transistors

Transistors are the key active components in all modern appliances. The importance of transistors in today’s society is mainly because they can be mass-produced using a highly automated process, thereby greatly reducing unit production costs.
