## Description

The basic concepts of electricity, dating back to over two thousand years, were unveiled by early scientists. Over the years, scientists have unlocked the nifty mystery in electricity by studying and analyzing the concepts of electricity using various scientific procedures or methods. Electricity has contributed immensely to the birth of civilization. Electrical energy is a common form of energy that can be found in large amounts in places like power stations and in little amounts in consumer devices like the calculator. Every home-based electronics and electronic device has the basic concept of electricity in direct current (commonly known as DC), which is essentially the movement of electrons through conductive materials. This course explores the basic fundamentals of a direct current circuit. You will be shown the laws and theorems in DC circuits formulated by early scientists. Upon that, you will be introduced to the nature of electricity and equations to facilitate your understanding of electricity.

Conductors, in simple terms, are materials (usually metals) that allow the free flow of electrons through them. There are several conductive materials that differ in nature which consequently affect the rate at which they allow electrons to flow through them. In this course, you will be shown several conductive materials including the ones that are suitable in the modern-day application of electricity. As there are materials that allow the free flow of electrons through them, there are also materials that do not allow the free flow of electrons through them. Such materials are known as insulators. You will learn about insulators and why they do not allow the free passage of electrons through them. Furthermore, you will learn about Ohm’s law and how it can be used to calculate components such as current, voltages and resistors across a circuit. In addition, you will gain an understanding of the arrangements of resistors (materials that allow a certain amount of electric charge to pass through them) across a circuit and determine the sum total. You will also be introduced to circuit theorems such as Norton’s theorem and Thevenin’s theorem as well as the analytic method used to analyze several DC circuits.

The capacitor is an electrical component that stores energy in an electric field. Well, why does a capacitor store energy and not charge? You'll discover the reason in this course and how capacitors are arranged across a circuit. Conversely, magnets are materials that generate a magnetic field. Though invisible, they have forces that can pull ferromagnetic materials. However, the phenomenon associated with magnetic fields that arise from the motion of electric charges is known as 'Magnetism'. This course will in detail explore magnetism including various equations used in calculation pertaining to electromagnetism in DC circuits such as magnetic flux, reluctance and permeability of a material. Furthermore, you will be introduced to Faraday’s law of induction and inductance. An understanding of basic math and linear equations is required to take the course. This course is for learners willing to understand the basic concepts of DC circuits of electricity.
