This free online course examines the basics of electricity, transformers, electrical machines and digital electronics.

The advent of electricity in homes, offices and industries marks the beginning of the modern age of technological development. Electricity has become such an essential part of our contemporary lives that we cannot imagine a world without it. It has been described as one of the "good fortunes that science has given to man," and the development of any country is measured by the rate of its electrical energy consumption. But electrical energy is not visible. As such, electrical engineers must study models from physics and mathematics to help them understand the mechanics and applications of electricity.

This course highlights the fundamental ideologies of the core elements of electrical engineering, including the theories and principles of energy conversion, transmission and utilisation. We study atomic theory, electromotive force, conductance and conductivity, Ohm's law and more. Moreover, we dissect work, energy and power before treating DC networks and network theorems. We investigate the three classifications of DC circuits and also show you how to read and connect circuit diagrams in experimental or real-world scenarios.

Finally, we explain the mathematical method for nodal analysis and the system for calculating the current flowing through a planar circuit (i.e., mesh analysis). Then, you will learn about the superposition, Thevenin's and Norton's theorems of linear and terminal networks. We will delve into single-phase AC circuits and electrical machines to study the characteristics and applications of DC generators, motors and transformers. Enrol today and start learning.
