EVALUATION

This evaluation section carries the unit's complete end-of-chapter assessment, split into four parts exactly as printed in the textbook: Part I, Multiple Choice Questions (15 questions, each with four options and an answer key at the end), testing quick recall and single-step calculation across every topic in the unit; Part II, Short Answer Questions (21 questions), testing definitions and short conceptual statements such as Kirchhoff's rules, Joule's law, and the various thermoelectric effects; Part III, Long Answer Questions (8 questions), requiring full derivations such as the microscopic and macroscopic forms of Ohm's law, the Wheatstone's bridge balance condition, and the working of the metre bridge and potentiometer; and Part IV, Numerical Problems (14 questions, each with the book's own final numerical answer given), requiring the full quantitative machinery of the unit -- current density and drift velocity, resistor networks, Kirchhoff's-rule circuit analysis, internal resistance, a …
