John Whitfield

John Whitfield spent 30 years as a lecturer at Norwich City College of Further and Higher Education, where he gained very wide experience in teaching electrical installation, electrical craft practice, electrical technician's courses and the Ordinry and Higher National Certificate and Diploma courses. His insight into the needs of students in technical education and his wide experience of teaching methods enabled him to base the earlier editions of this book on well-proven techniques. John continued to work on his books and technical papers until his death in 2019 at the age of 89 years.
