Course Description

This course focuses on the fundamental concepts of electrical and electronics engineering, spanning circuit theory, AC/DC analysis, and semiconductor devices. It systematically examines basic circuit laws and network theorems, moves through AC circuit analysis and single/three-phase systems, and progresses into semiconductor devices- covering diodes, transistors, and operational amplifiers/oscillators- concluding with their practical applications in power supplies, switching, and waveform generation.

Course Objectives
