Today in this post I’ll be writing about the electricity and magnetism books that I feel might be good considering whiling studying this subject for your undergraduate exams and also for when you appear for entrance exams like JAM for getting admission in masters in physics from good university or institute
ELECTRICITY AND MAGNETISM by A Mahajan, A Rangwala :- This is the first book in my list and I really like this book as it is extensive in its content and things are explained pretty clearly. You can consider this book for its comprehensiveness. You can take a look at the preview of this book here
We already know the statement of Ohm’s Law which is
“If the physical state of the conductor (Temperature and mechanical strain etc.) remains unchanged, then current flowing through a conductor is always directly proportional to the potential difference across the two ends of the conductor”
Insulators have very wide forbidden energy gap nearly of the order of 5eV or more.
Because of this very high energy gap it becomes impossible for electrons present in valence band to cross the gap and reach to the conduction band and this makes electrical conduction a practical impossibility in insulators at room temperature.
