The free online course on the application of phasors in AC circuit analysis and the concept of three-phase voltages.Publisher: NPTEL
CertificationView course modules
In this course, you will learn about the concept of phasors and how they are applied as parameters in AC circuit analysis. The superposition theorem, as well as the Thevenin's theorem and Norton's theorem with respect to steady-state analysis, will also be covered in this course. Then, this course will teach you about the concept of mutual inductance, and energy in a coupled circuit is measured.
Then, this course will introduce you to the concept of three-phase circuits as well as the phase sequence of three-phase voltages. The wye-connection and delta-connection, as well as the various possible connections for three-phase voltages, will also be covered in this course. Lastly, this course will teach you about the balanced wye-delta connection and balanced delta-wye connections, as well as the elements of an unbalanced system.
This course is helpful for learners who want to understand how theorems like the Thevenin's theorem, Norton's theorem and the superposition theorem are important in a sinusoidal steady-state analysis. Learners can also gain an understanding of the concept of three-phase voltages and the implications of their phase sequence. Begin this course now to learn the various ways three-phase voltages can be connected.Start Course Now
