Practical exam (30 marks)
Split between external evaluation (15 marks: two experiments worth 5 marks each, one from each section, plus a 5-mark viva) and internal evaluation (15 marks: practical record 4, project work plus viva 8, sessional/continuous assessment 3).
The practical syllabus lists 20 prescribed experiments across two sections, including refractive index measurement (microscope, mirror-lens combinations, prism), focal length determination for mirrors and lenses, Ohm’s law verification, meter bridge resistance measurement, potentiometer experiments (comparing EMFs, internal resistance), galvanometer conversion to ammeter/voltmeter, and characteristic curves for p-n junction and Zener diodes.
