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

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.
