The modern world is a place that simply cannot exist without the phenomenon of electricity. It is a primary requirement everywhere, whether it’s schools, workplaces, factories or our homes. An understanding of electricity and its fundamentals is hence of prime importance especially for professional technicians. If you are looking to gain an understanding of or revise your knowledge of the building blocks of electrical technology, then you have come to the right place. This course is designed to develop a comprehensive understanding of the rudimentary concepts of electrical technology. It kicks off with the basic concepts of the various types and properties of magnetism. The use of the Earth’s magnetic field, along with the various types of magnetic materials, are discussed. Having studied magnetism, we now move on to the interaction between electricity and magnetism. Electrically induced magnetism and magnetically induced electricity will be analyzed in detail, along with key illustrations, diagrams, and formulas for better understanding. Electrical items such as galvanometers, toroids and solenoids will also be discussed and explained with clear illustrations.

Are you familiar with atoms, electrons and neutrons? Or the definitions and formulas of everyday terms like work, energy and power? These are the building blocks we cover next in the course. An introduction to the most basic particle, called the atom, will be described. Along with atoms, the learner can also investigate charges and their use in generating electricity. Current is a word we are all familiar with, but this course will help properly define the term and its uses. Then, the learner will move on to the key topic of circuit parameters: resistance, inductance and capacitance. The definitions, types, measures and uses of all three parameters will be discussed in detail. The basic laws of electric current and DC circuits will also be analyzed. Have you ever been in a hazardous situation at home or the workplace involving electricity or electric current? This course will provide all the information regarding the hazards of electricity and the necessary preventive measures in order to protect yourself and those around you from them.

It is extremely rare to find an electrical appliance these days without a resistor, capacitor or inductor within it. These devices and their functionality are a key part of electrical technology. The learner will be analyzing these components individually and their combinations with AC circuits in both series and parallel combinations. Towards the later section of the course, the discussion moves towards AC voltages and distinguishing between various network elements. Circuits will be analyzed in detail including three-phase circuit systems. These circuits and elements will be described along with their key formulae, diagrams and illustrations to make sure you fully understand these basic concepts. The use of electricity has become so common in today’s world that one often takes these basic concepts for granted. However, after going through this online course, you can not only apply them in your professional life but also in your daily life with the electrical appliances surrounding us. So don’t waste any more time - start your learning journey with this free online course!
