**06-ELE-15/25 - BASIC ELECTRICAL ENGINEERING [BEE]**

1) Try to understand all units atleast to get the concepts even if you don't plan to study them for exams.

2) Some concepts might just feel out of reach. Try some animations and videos to understand the topic.

3) Every concepts which you learn in this subject will have to stay with you forever...exams --> further eee subjects --> placements --> work. If your basic concepts are clear, the path further makes more sense.

4) Text Books[VTU RECOMMENDED]:

E. Hughes; "Electrical Technology", International Students 9th Edition, Pearson, 2005.Rajendra Prasad, “Fundamentals of Electrical Engineering”, Prentice- Hall of India Pvt. Ltd., 2005, ISBN: 81-203-2729-2.5) Other Reading:

NOTE:Don't buy more than 2 books as "more books you refer, more confused you are, less you understand the real subject". Use Libraries and www.books.google.co.in for reference study from other books. Keep atleast one BEE book handy for your life. Don't sell textbooks. Save them for reference.
