What is the difference between electrical appliances and electricity?

Electrical engineering is a technology, an industry. Electrical appliances, on the other hand, are tangible substances; they are devices. The difference between the two is the same as the difference between electricity and electrical equipment.

I. Classification methods of electrical appliances: 1. Classified by operating voltage into high-voltage electrical appliances and low-voltage electrical appliances； 2. Classified by operation mode into automatically switching electrical appliances and non-automatically switching electrical appliances ； 3. Contact electrical appliances and contactless electrical appliances are classified according to executive functions. Any electrical device that, in response to specific external signals and requirements, automatically or manually connects or disconnects circuits, continuously changes circuit parameters, and thereby enables the switching, control, protection, detection, and regulation of circuits, is referred to as an electrical appliance. II. Electrical engineering is a science that uses electrical energy, electrical equipment, and electrical technology to create, maintain, and improve defined spaces and environments

Any electrical device that, in response to specific external signals and requirements, automatically or manually connects or disconnects circuits, continuously changes circuit parameters, and thereby enables the switching, control, protection, detection, and regulation of circuits, is referred to as an electrical appliance. Classification methods of electrical appliances: 1. Classified into high-voltage electrical appliances and low-voltage electrical appliances based on operating voltage levels ； 2. Classified by operation mode into automatically switching electrical appliances and non-automatically switching electrical appliances ； Contact electrical appliances and contactless electrical appliances are classified according to executive functions. Electrical engineering is a science that uses electrical energy, electrical equipment, and electrical technologies to create, maintain, and improve specific spaces and environments. This is what is stated on Aiwen Knowledge People

Electrical engineering covers a very wide area; it includes electrical appliances, and electrical engineering is an industry, while electrical appliances are products.

　Electrical appliances: This term refers to all devices that use electricity. From a technical perspective, it mainly denotes electrical apparatuses, equipment, and components used for connecting and disconnecting circuits, as well as for modifying circuit parameters, in order to control, regulate, switch, monitor, and protect circuits or electrical devices. But now this term has been widely extended to the civilian sector; from the perspective of ordinary people, it refers mainly to various electrical devices that are commonly used in households to facilitate daily life, such as televisions, air conditioners, refrigerators, washing machines, and various small household appliances...... etc. Electricity: generally refers to power-related equipment as well as technical devices used in industry.

The control logic in the early days was primarily based on pneumatic components, and the term \"electrical\" came into use as it evolved towards electric control.

The old post by Banzhu already explains it. . http://bbs.hcbbs.com/viewthread.php?tid=257818&highlight=%B5%E7%C6%F8%2B%2B%B5%E7%C6%F7

Electrical appliances: ∶ Household or office items that are operated using electricity ∶ Instruments, devices, accessories, and other components that serve as part of electrical installations or are related to them. Electricity: Relating to electricity, associated with electric power
