Group 1: Experiment from Higher Secondary knowledge of Physics
1 . Determination of thermal conductivity of a good conductor by Searle’s mothod.
2. Determination of thermal conductivity of a bad conductor by Lees and Chorlton’s method.
3. Determination of dispersive power of the material of given prism.
Group 2: Experiments on General Properties of matter
4. Determination of Young’s modulus by Flexure method and calculation of bending moment and
shear force at a point on the beam.
5. Determination of modulus of rigidity by static/ dynamic method.
6. Determination of co-efficient of viscosity by Poiseulle’s capillary flow method.
Group 3: Experiments on Electricity and Mangentism
7. Determination of dielectric constant of a given dielectric material.
8. Use of Carry Foster’s bridge to determine unknown resistance.
9. Determination of resistance of ballistic galvanometer by half deflection method and study of
variation of logarithmic decrement with series resistance.
10. Determination of the thermo-electric power at a certain temperature of the given thermocouple.
11. Determination of specific charge (e/m) of electron by J.J. Thomson’s method.
a) A candidate is required to perform 3 experiments taking one from each group.
Initiative should be taken so that most of the Experiments are covered in a college in the
distribution mentioned above. Emphasis should be given on the estimation of error in
the data taken.
b) In addition, a student should perform one more experiments where he/she will have to
convert the non-electrical signals (viz. Temperature, Intensity of Light, Pressure etc. ) present
in an Experiment into electrical signals and measure them with the help oh Multi-meters/
Oscilloscopes. Student should calibrate the Sensor for Experiment before use.
c) Innovative experiment: One more experiment designed by the student or the concerned
teacher or both.
Note:
i. Failure to perform each experiment mentioned in b] and c] should be
compensated by two experiments from two different groups mentioned
in the above list.
ii. At the end of the semester report should sent to the board of studies
regarding experiments, actually performed by the college, mentioned
in b] and c]
i. Experiment in b] and c] can be coupled and parts of a single
experiment.
