Basic Electrical Technology

Basic Electrical Technology. Instructor: Prof. L. Umanand, Department of Electrical Engineering, IISc Bangalore. The course is structured into three components: electrical essentials, electromagnetic domains, and electro-magneto-mechanical domains. The first part of the course will focus on electrical essentials which are really essential for any electrical engineer to operate on the electrical technology. The second part will focus on electrical equipments in the electromagnetic domains, mainly transformers. The third part focuses on the electro-magneto-mechanical domain. What it basically means is the energy flows through the electrical domain, the magnetic domain and the mechanical domain which are the machines. (from nptel.ac.in)
