A text for courses in electrical and electronic principles, circuit theory and electrical technology. The coverage takes students from the fundamentals of the subject, up to and including first degree level. Thus, it should be suitable for students with a typical high school background studying engineering for the first time, and suitable for pre-degree vocational courses, especially where progression to higher levels of study is likely. Theory is kept to a minimum, and a firm emphasis is placed on problem-solving skills. This second edition includes new material on semiconductor diodes, transistors and operational amplifiers. The content is matched to UK syllabuses, including the Advanced VIC (GNVQ), BTEC National (2001 specifications) and BTEC Higher National Engineering (phase 2 unit specifications).
