What is Electronics?
Electronics is a branch of physics that deals with the emission, behaviour, and effects of electrons in materials. OR
Electronics is the study of how to control the flow of electrons. NB: The various electronic components connected to each other to form systems or circuits are called Electronic systems (Electronic circuits). An electronic circuit is used to perform a wide variety of tasks. The main uses are:
- Conversion (AC to DC) and distribution of electric power
- Controlling and processing of data
Electronic Component
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields. Examples include power sources, resistors, capacitors, diodes, transistors, and integrated circuits.
Types of Electronic Components
(a) Passive Electronic Components
These consume energy but do not produce energy. They include:
- Power sources (battery or generator)
- Resistors
- Capacitors
- Inductors
(b) Active Electronic Components
These consume energy in the form of voltage or current and supply energy in the same form. They include:
- Diodes
- Transistors
- Integrated circuits
