Learners enrolled: 2703
This comprehensive course on “Principles of Electrical Sciences” is mainly for undergraduate first-year engineering students from all branch of engineering. The content of the course covers almost all the topics of basic electrical engineering, ranging from DC and AC circuits to electrical machines and transformers. In addition to this, low voltage electrical installations and elementary calculations for energy consumption have also been covered so as to prepare the students for an in-depth study later. In this course, easy explanation of topics, plenty of examples and illustrations are also discussed. This course “Principles of Electrical Sciences”, will work as positive catalyst to boost high-quality knowledge in the field of electrical engineering.
