It contains fundamental information on the theory and calculations of direct and alternating current circuits and on magnetic circuits.
After centuries of research, scientists have concluded that all things around us, despite their diversity, consist of a limited number of simple elements.
surely, there are many well qualified practicing electrical engineers who have talked at one time or other about seeking licensure but who have not taken the necessary steps to become registered. perhaps they have thought licensure would somehow "disapper," or " go away," but were left with the distict feeling they would have to do something about is some day
The modern transformer is a sophisticated piece of electriccal equipment. it consists of a large number of components varying with transformer type, application and capacity
