Electrical Fundamentals

Are you aware that every substance around you is made up of the tiniest of particles called atoms? And that these atoms are responsible for creating electricity? If not, then you have come to the right place. This course provides you with all the knowledge of electrical technology fundamentals and gradually builds on those rudimentary concepts. We kick off with a basic understanding of atoms and particles that make up an atom ie charges. Concepts like valency, conductors, semiconductors, and insulators will be analyzed. Building on these concepts, the focus moves to the description of current, electromotive force (EMF), work, and energy. Along the way, we will be looking at formula charts and illustrations of how these concepts are applied, not just at the workplace but also in many appliances around us on a day-to-day basis.  

Moving on with your learning, our focus shifts towards important electrical devices called resistors, capacitors, and insulators. An analysis of each of these will be carried out in detail. The key principles behind their workings, application and types will all be part of the learning material in this section. Some important laws and effects associated with these devices will also be discussed. Important items like Joule’s law, Ohm’s law, and Kirchhoff’s current and voltage law will also be discussed. Over the years, scientists also discovered some important effects of electric current during their experiments. Some of their key findings include the chemical effect of electric current. The Peltier, Thomson, and Seebeck effects were all important observations made along the way of electrical theory evolution. All these effects will be part of your course material and will be explained with illustrations in detail.

Towards the final part of the course, your attention will be directed towards DC (direct current) circuits. The sources of DC current, both in series and in parallel, will be discussed. Another key aspect of DC circuits is a voltage and current divider, which will be analyzed in-depth. Finally, static electricity and stray currents will be looked at in detail. The various sources and application of both static electricity and stray currents will be described. Are you aware of the hazards of electricity? We have all heard of cases of electrical shock by wires or lightning. This course will not only help you understand the dangers of electrical shocks and hazards but it will also provide you with the necessary safeguards and precautions necessary in order to prevent such incidents from happening. We live in a world that is hugely dependent on electricity: not just our workplaces but our houses and lives are filled with items that cannot function without electricity. Whether you want to understand the concepts of electricity in order to satisfy your curiosity or you are looking to develop a career in electrical science, this course has got you covered!
