Electrical Engineering is such a branch of Engineering, where every day at every corner of the world new inventions and new idea of innovation for development of our society is a continuous process. I feel from my short experience of five years of my teaching career that students should learn the basis of Electrical Engineering very strongly, because if the base of the learning will be strong then building of the knowledge will be that much strong. I am very much glad to present this book to my reader which might give you idea about dealing with real problem practically, enhance your knowledge and try to cover up the void of you knowledge.
