Electrical is electrical, can it be understood as the weather in the sky? Engaged in the electrical industry for many years, but the definition and extension of its definition are not many. I have a discussion of electrical definitions in the novice class, Electrical/Electrical Engineering (EE), which covers microelectronics, photonics, and microcomputer applications. But it seems to be biased by the electricity we talked about. However, one can be sure, what everyone agrees is that electrical appliances are specific object images, and electrical is an intangible classification concept! Electrical appliances contain electrical appliances.
"Electrical", the foreign language translation also, at the beginning of the Western industry, the power machinery was driven by steam turbines, and later had electricity, so "electric", began to refer to industrial power, but now there is no steam The turbine is gone, so it is simply electric. The term "electrical" has been used to it, so it is used! Nothing deep!
The gas in electricity is referred to as "compressed air." In industrial automation, there are three types of equipment that need to be moved, such as electric, pneumatic transmission, and hydraulic transmission. Electric and pneumatic are the most widely used power sources, and the two are used together to complete automation. Therefore, it is called: electrical automation.
In addition, the word "electricity" originated in Japan, and Japan also translated from Western languages, thinking that "electricity", the state of electricity is also. Therefore, electricity is a science that studies the state of electricity.
