ELECTRICAL TECHNOLOGY SECOND EDITION
This book has been written to assist students enrolled in the first ycar of any course leading towards appropriate gualification as technicians in the fields of electrical engineering, electronics, instrumentation or control engineering, or allied fields. It covers, in particular, matters connected with direct-current phenomena. While the book is intended primarily as a textbook for the abovementioned courses, it would be of assistance as a reference book to anyone engaged in electrical industry, particularly since it has been based entirely on the International System (SI) of Units (the most recently promulgated specific form of the metric system), which has now been adopted by most of the world's countries and scientific organisations.
The subject-matter covered in this book is aimed to assist any student who is very likely facing a subject of an entirely electrical nature for the first time in his particular course of study. As such, this book will form the basis of many future subjects which will be covered in later years of the same course. It presents the fundamental principles of electrical and electronic engineering in relation to their practical application in the engineering field. The same principles will be used extensively in other subjects as well, and therefore it is essential that the fundamental information presented in this book should be well absorbed: otherwise difficulties might possibly arise in studying subseguent subjects due to lack of an adeguate background knowledge. It is hoped that the practical and realistic flavour of the problems and exercises will help to dispel any doubts about the value of the subject being studied: it is indeed the foundation stone of any course in this branch of engineering.
