Scheme of Physics Practical Examination Duration: 3 hours Maximum Marks: 20

There will be a practical examination of 20 marks apart from the theory examination. The distribution of 20 marks is as follows: (i) (ii) (iii) Viva Record Book Two Experiments 4 Marks 2 Marks 14 Marks

Note: There are 30 experiments in three Groups A, B and C. In the practical; examination candidates has To do two experiments which should not be from the same group and each experiment carries 7 marks. GENERAL INSTRCTIONS FOR PHYSICS PRACTICALS A. Instructions for the candidates.

1. Record your observations by pen (ink) or ball point and draw your diagrams by pencils. Calculations should be done by pen or ball point pen. If some observation is wrongly recorded, it should be rewritten. Do not over-write or erase any observations. 2. one principal observation must be shown to the examiner, otherwise the experiment will be treated as incomplete. Calculations may be done, using preferably log tables. 3. Draw labeled diagrams and graphs wherever necessary. 4. Candidates allotted electricity or electronic experiments must draw circuit diagrams and get them checked by the examiner before starting the experiment. 5. Candidates performing optics experiment must draw the ray diagrams and get them Checked by the examiner before starting the experiment. 6. Candidates will be required to perform two experiments in 3 hours. These two experiments should not be from same group. B. 1. 2. 3. 4. 5. General Instructions for Examiners The above “instructions for the candidates” are to be announced to the candidates before the start of the examination. For each batch of 20 candidates, the student will be allotted two experiments from two different groups – A, B and C. The examiner is to select different combinations for different batches. The examiner must sign after checking, at least one observation in each experiment. The distribution of marks for each experiment will...
