Basics of Electricity: Resistance, Inductance & Capacitance

Develop an understanding of the basic elements of electrical circuits and their behaviour with this free online course

Publisher: ADU
This course takes you through resistors, capacitors, and inductors which are the three main building blocks of electrical circuits. The learner will examine these components and their functionality both in series and in parallel. The pairing of these components with one another along with their phasor representations and impedance diagrams will be analyzed. Key terms such as resonance, bandwidth, and Q-factor of circuits will also be defined.

Are you aware of the three main components of electrical circuits? And do you know what role these components play in our daily lives both in our homes and our workplaces? If you are curious about finding the answers to these questions then you have clicked at just the right place. This course will guide you through the main components of electrical circuits i.e. Resistors, inductors, and capacitors. An analysis of these components will be carried out in both series and parallel connections. You will be kicking off your analysis of circuits with an explanation of series and parallel circuits individually. The grouping of series and parallel circuits will also be discussed by the learner along the way. The combination of resistors, inductors, and capacitors in A.C. circuits will be explained during the course of your studies. Video illustrations, diagrams, and key formulae will be provided along the way in order to ensure the learner gets to fully grasp the concepts and develop a solid foundation to build on.

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

As we head towards the final section of the course, the learner will be analyzing resonance in both 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 topic of this course will take you through the power factor and the concepts of active and reactive components of power. The derivation of instantaneous power equations of A.C circuits will also be provided during the course. Whether it is the use of circuits in our daily lives or in workplaces, R, L, C circuits and their understanding 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. So don’t look any further.
