Electronics 101: Introduction

In this tutorial, we provide the very basic fundamentals and also give you a thorough understanding of the principles and operation of electronic components and devices. This means, as a beginner, you don’t need prior knowledge about electronics to follow along.

In the first chapter, we will cover the basics of electricity and a few terminologies and then we’ll move on to simple, intermediate and advanced electronic components and circuits. The electronic components that we’ll learn about in these tutorials will be used to build simple circuits and projects, this way as a beginner you will be able to know how to apply and use them in real life.

Before we embark on this course, I’ll advise you to buy a starter kit with a few basic electronic components to help you build your own circuits and projects as you follow along with the tutorial series. Alternatively, you could use simulation software such as Proteus Design SuiteNI-Multisim, or EasyEDA, but either way, you’ll get to learn a great deal about electronics.

 

These articles will help you learn how to download and install circuit simulation software on your machines:

 

 

In this introductory course to Electronics, we are going to cover the following topics:

Lesson 1:  Electricity and how it works

In this chapter, we cover the basics of Electricity and how it works and we’ll mainly concentrate on current electricity i.e. what powers our gadgets. Our main intention here is to understand how electricity flows from a power source through wires, spinning motors, and powering our gadgets.

Lesson 2:  Circuit Basics – Open Vs Closed

In this chapter, we cover the basics of an electric circuit in greater detail. We’ll understand what voltage is and how it works and we’ll also look at the two special cases of electric circuits ie. short and open circuits.

Lesson 3 Current – AC Vs DC

In this chapter, we look at the two forms of conveying electric power from one point to another ie Alternating Current (AC) and Direct Current (DC) and we’ll also cover how the two forms (AC and DC) are generated and their respective applications in our day-to-day lives.

Lesson 4:  Resistance, Voltage, Current & Ohm’s Law

In this chapter, we explore the basics of Voltage, Current, and Resistance and how they relate to each other using Ohm’s Law (the basis for the analysis of any electric circuit.). These are the 3 main building blocks that are required to manipulate and fully utilize electricity.

Lesson 5:  Resistors

In this chapter, we look at Resistors, what they’re, the units of resistance, the schematic symbol for resistors on a simulated electric circuit, the different types of resistors, how to read resistor values, how to connect resistors in series and parallel, and finally the different applications of resistors.

Lesson 6:  Capacitor Basics

In this chapter, we look at Capacitors in greater detail, we cover how capacitors are made, how they work, the units of capacitance, the different types of capacitors, how they connect in series and parallel configurations, and their common applications in our day-to-day lives.
