The book 'CO-RE OF ELECTRICAL ENGINEERING' has been written with this
objective. It is hoped that it will serve as a handy document for quickly finding the important
constants and the relations needed to solve an Electrical Engineering problem in hand, or to
develop other inter-relationships. The subjects covered are circuits and networks, field theory,
electrical engineering materials, instruments and measurements, control systems, electrical
machines, and power systems. The coverage of constants and the formulas are, of course, not
exhaustive, but those which are basic in nature, or are quite often needed have been included.
No detailed derivations of the relations have been given. Only very brief explanations or the
key points of some of the relations have been presented. It has been assumed that the reader
knows and understands the subject. He only needs to refresh.
