Common Symbols And Names Of Electrical and Electronics

Different abbreviations of electrical and electronics appear in different fields. These characters are used in different types of electronics devices, different circuits, tools, and functions.

Besides, these characters are almost exclusively in the electrical, electronics industry and various machine features or nameplates.

It is expected that this article will be very helpful for new students in the electrical and electronics department. Besides, I am starting to write this article out of thoughts that benefit everyone.
