PRACTICALS

NOTE: Students are expected to perform eight experiments in the semester. Out of these eight experiments, two experiments will be set in the examination paper.

The examination will be conducted for  6 hrs. The distribution of marks in the practical examination will be as follows:

1. Two experiments                                 :           30 marks each

2. Distribution of marks will be as follows :

                 Figure /Formula/Theory                :           7

                 Observations/Calculations              :          16

                 Result /Result  Analysis                  :          5

                  Precautions                                     :          2

3. Viva -Voce                                          :           10

                    Total                                                         :         70 marks
