Students are introduced to a variety of disciplines that serve as the cornerstone of their engineering education during the first semester of a B.tech degree. Basic Electrical & Electronics Engineering is one of the subjects. For students interested in a career in this sector, this topic offers an overview of the fundamental concepts of electrical and electronics engineering. The main ideas and subjects covered in the RGPV B.tech Semester-I Basic Electrical & Electronics Engineering course will be discussed in this post.
A fundamental grasp of electrical and electronic concepts and their applications in engineering is what the Basic Electrical & Electronics Engineering course attempts to give students. The goal of this course is to provide students with the information and abilities needed to evaluate and construct simple electrical circuits and systems. The following are the course’s objectives:
1. To familiarise students with the basic ideas of electrical and electronics engineering, such as electrical numbers, units, and laws.
2. To improve students’ analytical and problem-solving skills in relation to electrical circuits and systems.
3. To equip students with the skills necessary to construct and evaluate fundamental DC and AC electrical circuits.
4. To get pupils familiar with the attributes and workings of electrical devices such transformers, generators, and motors.
