ELECTRICAL TECHONOLOGY

Preface to the Twenty-second Edition Of Electrical Techonology :


The primary objective of Vol. I of A Textbook of Electrical Technology is to provide a comprehensive treatment of topics in ‘Basic Electrical Engineering’’ both for electrical as well as nonelectrical students pursuing their studies in civil, mechanical, mining,MACHINE DRAWING
textile, chemical, industrial, environmental, aerospace, electronic and computer engineering both at the Degree and Diploma level. Based on the suggestions received from our esteemed readers, both from India and abroad, the scope of the book has been enlarged according to their requirements. Almost half the solved examples have been deleted and replaced by latest examination papers set upto 1994 in different engineering colleges and technical institutions in India and abroad.


Following major additions/changes have been made in the present
edition :
