Practicals

At the end of the course, the student will be able to:

CO 116: Apply the various procedures and techniques for the experiments.

CO 117: Use the different measuring devices and meters to record the data with precision.

CO 118: Apply the mathematical concepts/equations to obtain quantitative results.

CO 119: Develop basic communication skills through working in groups in performing the laboratory experiments and by interpreting the results.

Approach in teaching: Demonstration, Group activity, Discussion ,Conduction of Experiments, Asking viva voce questions.

 

 

 

 

 

 

Learning activities for the students:

Performing Experiments, Analysis and interpretation of observations, Record preparation.

Class test, Semester end examinations, Viva-voce, Practical record File.

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
