Introduction to Basic Electronic and Electrical Engineering

1. Quick Overview

Basic Electronic and Electrical Engineering (BEEE) is a foundational subject that introduces students to the basic principles of electrical and electronics engineering. It provides the fundamental knowledge required to understand electrical circuits, electronic devices, electrical machines, power systems, and modern electronic technologies.

This subject combines the concepts of electrical engineering and electronics engineering to help students understand how electrical energy is generated, controlled, transmitted, and utilized, along with how electronic devices process and control electrical signals.

The concepts learned in this subject serve as the building blocks for advanced EEE subjects studied in later semesters.

3. Working Principle / Concept

Basic Electronic and Electrical Engineering combines two important engineering disciplines.

Electrical Engineering

Electrical Engineering mainly deals with electrical power.

It includes:

  • Power generation
  • Power transmission
  • Power distribution
  • Electrical machines
  • Electrical installations
  • Electrical measurements

Electronics Engineering

Electronics Engineering mainly deals with electronic circuits and signal processing.

It includes:

  • Semiconductor devices
  • Diodes
  • Transistors
  • Integrated Circuits (ICs)
  • Digital Electronics
  • Communication Systems

How Both Work Together

Modern electrical systems require electronic control for better efficiency, automation and safety.

For example:

  • A ceiling fan uses an electric motor (Electrical Engineering) while an electronic regulator controls its speed (Electronics Engineering).
  • An electric vehicle uses an electric motor for propulsion and an electronic controller for speed and battery management.
  • A solar power system generates electricity using solar panels while electronic converters regulate the output voltage.
