Lab Course (Practical)

The students will be able to –

CO29: Demonstrate measurement skills in a physics laboratory.

CO30: Analyze the measurement results to draw valid conclusions  with honesty.

CO31: Have oral and written scientific communication, and think critically and work independently.

CO32: Develop the skill to determine elastic constants like Young’s modulus , modulus of rigidity etc by different methods.

CO33: Understand the concept of  conversion of galvanometer to ammeter and voltmeter ,R-C circuit, LR circuit, specific resistance ,electromagnetic induction ,charging and discharging of a condenser, Carey Foster’s bridge and  Faraday’s Law by performing experiments. 

Approach in teaching:

Demonstration, Group activity, Discussion, Conduction of Experiments, asking Viva-voce questions.

 

 

Learning activities for the students:

Performing Experiments, observations,  Analysis and interpretation of results

Class test, Semester end examinations, Viva voce, Practical record file
 
 
 
Students are expected to perform any eight experiments from the given list. Two experiments out of the eight will be set in the examination paper.
The duration of the Practical Examination shall be 5 hours.
 
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
