This third edition has been fully revised and expanded from the author's Electrical Principles IV to cover all the material for both years of study for a BTEC HNC/D in Engineering. Each topic is carefully explained and then illustrated by a large number of practical examples with fully-worked solutions. Each chapter also contains exercises, with solutions at the end of the book, to reinforce the theory. Higher Electrical Principles is essential reading for all students taking electrical principles level IV and V for HNC/D courses in electrical, electronic, communication and computer engineering. It will also be of interest to first and second year undergraduates studying engineering degree courses.
