This textbook is a specialised, high-yield guide focusing on the Experimental Physics and Laboratory Techniques syllabus of the UGTRB Physics Examination. Spread across 15 chapters, it comprehensively covers error analysis, measurement uncertainties, data analysis, least squares fitting, dimensional analysis, length measuring instruments (vernier calipers, screw gauge, travelling microscope, optic lever), laboratory apparatus (Hare's apparatus, calorimeter, Barton's correction), optical experiments, moving coil and ballistic galvanometers, electrical measuring instruments, electrical test instruments (analog & digital multimeters), magnetic measuring instruments (tangent galvanometer, magnetometers), bridge circuits, AC measuring circuits, digital electronics in measurement, and laboratory techniques. Complete with solved numericals, viva-voce questions, and practice MCQs.
