In the civilian field, electrical appliances refer to power-consuming electrical equipment (ie, electrical equipment such as washing machines, televisions, and refrigerators). Academic definition: Any electrical equipment that automatically or manually turns on or off a circuit according to specific signals and requirements from the outside world, continues or continuously changes circuit parameters, and implements circuit switching, control, protection, detection, and regulation For electrical appliances. From the perspective of discipline division, electricity, electronics and electrical appliances are all electrical engineering disciplines. The term "electrical engineering" comes from Japan, and the gas comes from the translation of Western foreign languages. Electrical engineering is also electrical engineering. 1. Electricity: Electronics, electrical appliances, and electricity all belong to electrical engineering. It is an abstract concept, not specifically referring to a certain device or device, but referring to the entire system and the categories of electronics, electrical appliances, and electricity. 2. Electricity: Electricity is a strong part of electrical engineering. It mainly studies the supply of electrical energy (ie, the generation and generation system of electrical energy), transmission (power line transmission), and transformation (high and low voltage transformation, transformers, circuit breakers, contactors) Divided into high-voltage electricity and voltage distribution; 3. Electronics: Electronics refers to the weak current part of electrical engineering, which mainly studies the processing and transformation of information; electronics can be divided into two parts: electronic circuits and electronic systems. Electronic circuits (electronic components: electronic components used to make circuit boards and electronic designs, such as diodes, transistors, silicon, LED lights. Electronic devices: an electronic functional device composed of single and multiple circuit boards), electronic system: by The system composed of electronic equipment is the weak current engineering system 4. Electrical appliances: Electrical appliances are specific devices. In the narrow sense, electrical appliances refer to switches in the industrial field. In the civilian field, electrical appliances refer to power-consuming electrical equipment (ie, electrical equipment such as washing machines, televisions, and refrigerators). Academic definition: Any electrical equipment that automatically or manually turns on or off a circuit according to specific signals and requirements from the outside world, continues or continuously changes circuit parameters, and implements circuit switching, control, protection, detection, and regulation For electrical appliances. Distinguish electrical engineering from an engineering perspective 1. Power generation project: power plant construction (hydropower, thermal power, geothermal power, etc.) 2. High-voltage power transmission project: Responsible for high-voltage power distribution projects from power plants to various power grid areas, regions to provinces, cities and urban areas. Above 3KV voltage. 3. High and low voltage project: responsible for connecting high voltage electricity from urban high voltage power supply to unit, enterprise or community transformer and transformer project 10KV-3KV voltage of high and low voltage conversion 4. Power distribution project: Responsible for connecting the 380V output from the transformer to the power distribution room of each power building and factory building and the power distribution room to the power consumption place in each power unit. That is 380-220V voltage 4. Weak current engineering: namely electronic system engineering, connecting electronic equipment to form a system. Refers to all electronic system engineering below 110V. Electrical engineering and automation are generally divided into: power systems and applied electronics, that is, power electronics Power system and its automation: entering the power bureau but it must be a good school, otherwise it is not easy to find a counterpart job Power Electronics and Power Transmission: More and more power is transformed into the company, more tired
Hookah also known as waterpipe, narghile, argileh, shisha, hubble-bubble, goza, borry, qaylan, chica, and mada'a (Fig. 1) is a tobacco pipe with a long yet flexible tube that draws the smoke through water contained in a bowl.
A hookah is a type of water pipe that was crafted to be used for smoking shisha tobacco. Hot charcoal is used to heat the tobacco in the bowl
A hookahis a single- or multi-stemmed instrument for heating or vaporizing and then smoking either tobacco, flavored tobacco (often muʽassel), or sometimes cannabis, hashish, and opium.[3] The smoke is passed through a water basin-often glass-based-before inhalation
