Electronics – I

We are very glad to present the book “PHY– 302 (A): ELECTRONICS-I’’ in the hands of SYBSc students. The book is strictly written and complied according to the semester pattern syllabus framed by the Board of Studies in Physics, KBC NMU Jalgaon, for Second year BSc to be implemented from June 2019 and is written in lucid, simple language giving exhaustive details. Questions of various types are included at the end of each chapter. This will help in generating interest and thorough understanding of the subject. We hope, this book will be useful for the students and teachers.
