Chapter 39: Alternating Current introduces phasors, impedance, and resonance. Verma avoids complex numbers initially, using trigonometric methods, then gradually introduces the complex representation. Chapter 41: Electric Current through Gases touches upon discharge tubes and thermionic emission, bridging to modern physics. Chapter 42: Maxwell’s Equations —a rare feature in undergraduate-level Indian textbooks—presents the four equations in integral form, explaining the displacement current and the prediction of electromagnetic waves. This chapter alone elevates the book to a near-graduate level.
The book’s influence extends beyond exams. It teaches intellectual honesty: when a formula appears, you know why it is there and what assumptions underlie it. For instance, the formula for the capacitance of a parallel plate capacitor is derived with and without a dielectric, and the edge effects are openly acknowledged as approximations. H. C. Verma’s Concept of Physics (Volume 2) is not merely a textbook; it is a rigorous, compassionate, and intellectually thrilling companion. It refuses to coddle the student but also never abandons them. From the first Coulomb force to the last nuclear decay equation, the book maintains a single, unwavering standard: understand first, then apply. For anyone serious about learning physics—not just clearing exams—Volume 2 is an indispensable treasure. It stands as a testament to the idea that a great teacher, through the pages of a book, can ignite a lifelong passion for the laws of nature. Concept Of Physics H C Verma Volume 2 Full Book
The journey begins with Chapter 22: Coulomb’s Law and Electric Field , where Verma introduces the inverse-square law and the concept of electric field intensity. He carefully distinguishes between electrostatic force and gravitational force. Chapter 23: Gauss’s Law is a masterpiece of clarity—Verma uses symmetry arguments to derive field due to infinite line charges, sheets, and spheres without resorting to complex calculus initially.
