Learn about all the theories behind electrical/electronics and computer circuits, devices and components. Topics in this section range from beginner to advanced level topics. Knowledge of topics in this section will guide you in designing/building working circuits and writing structured programs. It will also help you in troubleshooting faulty circuits and debugging program codes.
Topics you need to get you started. Topics listed in this section will help you get grasps of the fundamentals of electronics and the concept of electricity. A good understanding of the topics in this section will go a long way in easing your understanding of the rest of the topics.
Analogue Electronics 1 (Passive Components)
Electronic circuits that operate on signals that can vary over a range of values with time (continuous signals) are called analogue circuits. In this section, we treat the theories behind the circuit behaviour of passive components used in electronics circuits. They are called passive components due to the fact that their behaviour in an electronic circuit is governed by their physical electrical characteristics and not by an external voltage or current signal.
Analogue Electronics 2 (Active Components)
Active components allow the flow of current flowing through them to be controlled via an external voltage or current signal. They have the capability of amplifying an input signal or switching current on or off in a circuit. This section will get you familiar with active electronic components; how to identify them, test them and use them in your circuit when the need for their function arises in your circuit designs.
Analogue Electronics 3 (Analogue Integrated Circuits)
In this section, we take a look at some integrated circuit components used in analogue circuit designs. Some of the integrated circuit components explained here form the basis of most circuits blocks or modules used in building more complex circuits.
By mapping a range of analog voltage levels into two discrete groups, we enter the domain of digital electronics. These two discrete groups of ‘1 and 0’ or ‘ON and OFF’ or ‘HIGH and LOW’, form the basis of working with digital electronic circuits. The topics in this section will set you on the right path in working with digital electronics.
