Circuits and Electrical Skills

Ningbo City College of Vocational Technology via XuetangX

Overview






The course of "Circuit and Electrical Skills" serves as a professional foundation course for majors such as applied electronic technology and intelligent control technology in vocational and technical colleges, and can also be used as a professional training course for relevant personnel in the maintenance electrician industry.

This course arranges learning projects based on specific practical processes. It has five learning projects, namely, safe use of electricity, assembly and debugging of multimeters, design and installation of lighting circuits, control wiring and measurement of three-phase AC motors, use and maintenance of transformers.

Through the learning and training of this course, you will possess common sense of safe electricity use in daily life, acquire necessary basic theories and applications of electrical engineering, grasp the basic knowledge of analyzing complex circuits, and possess the initial ability to quantitatively analyze and calculate complex AC/DC circuits, as well as certain electrical skills. This will lay a foundation for the learning of subsequent courses and the cultivation of electrical engineering application abilities.
