Electrical and electronic technology is a basic course for non-electrical engineering majors, including circuit model, AC and DC circuit analysis, motors, measuring instruments, analog electronic technology and digital electronic technology.

The basic course of electrical and electronic technology is advanced mathematics and college physics, which is usually taught in sophomore year and is a difficult course for engineering majors.

There are many teaching materials of electrical and electronic technology on the market, and the contents are similar. I suggest you use ready-made textbooks or find a thinner textbook as the basis, and refer to some professional textbooks of circuit, motor, analog electronic technology and digital electronic technology.
