Basics of Electricity: Resistance, Inductance & Capacitance

Are you aware of the three main components of electrical circuits? Do you know what role they play in our homes and workplaces? This course guides you through the main components of electrical circuits: resistors, inductors, and capacitors. An analysis of these components will be carried out in both series and parallel connections. You kick off with an examination of series and parallel circuits. The grouping of series and parallel circuits will also be discussed. Then, the combination of resistors, inductors, and capacitors in AC (alternate current) circuits will be explained. Video illustrations, diagrams, and key formulae will be provided in order to ensure you fully grasp the concepts and develop a solid foundation to build on.

Moving on, you will be introduced to phasor representation and impedance diagrams of RL and RC series-parallel circuits connected across an AC supply. An explanation of the time constants of RL and RC circuits will also be provided. Computation of the key formulas developed through the various circuit tests carried out will be shown. Along with video illustrations, the course provides detailed tables and procedures to understand RL and RC circuit tests in both series-parallel connections. Next, the RLC circuit will be the focus. Both RLC series and parallel circuits will be discussed along with circuit tests, diagrams, and procedures. The RLC circuit will also be looked at in connection with an AC supply. The key conclusions derived from circuit tests will also be discussed so that the output of those experiments can be learned in detail.

In the final section, you analyze resonance in series and parallel circuits and their calculations. The derivation of resonant frequency in series-parallel connections will be carried out. Key definitions of bandwidth and quality factors will also be looked at along with diagrams and formulas. The last module takes you through the power factor and the concepts of active and reactive components of power. The derivation of instantaneous power equations of AC circuits will also be provided. Understanding RLC circuits is a key topic for those interested in electrical technology. These rudimentary concepts will enable you to build a solid foundation for further application in both your academic and professional lives.
