A branch of electricity and physics. This paper mainly studies the formation and application of electricity. The word "electricity" comes from the Greek amber in the west and from the lightning phenomenon in China. Since the middle of18th century, the study of electricity has gradually flourished. Each of its major discoveries has aroused extensive practical research, thus promoting the rapid development of science and technology.

Electrical engineer refers to a professional electrical engineer who is engaged in survey, planning, design, power engineering construction, installation, debugging, technology development, experimental research, power generation and supply operation, maintenance, overhaul, power grid dispatching, power management, power environmental protection, power automation, technology management, etc.

Its job responsibilities are: organizing, coordinating and managing the installation and operation team; Check the load calculation of the whole plant and determine the number of main electrical wiring and chief editors;

Responsible for the design review of electrical system, the signing of technical agreement and the selection of electrical equipment; Responsible for supervising and organizing the installation, debugging and schedule control of electrical equipment;

Responsible for organizing the entry and unpacking acceptance of electrical equipment; Responsible for electrical operation management and personnel training; Responsible for the preparation of electrical post rules and regulations, operating procedures and emergency plans.

Electrical engineer refers to the professional and technical personnel who have obtained the Qualification Certificate of People's Republic of China (PRC) Registered Electrical Engineer and are engaged in electrical engineering design and related business.

The state implements a registration management system for professional and technical personnel engaged in electrical engineering design activities.

Registered electrical engineer has a wide range of practice, and can engage in supervision, bidding, bid evaluation and technical consultation of electrical specialty.

Engineers are divided into assistant engineers (junior), engineers (intermediate), senior engineers and professor-level senior engineers (researcher-level senior engineers and senior engineers). It is different from registered electrical engineers, who have to pass basic and professional examinations, while engineers are professional titles and need to be evaluated.
