Class 12th Physics Investigatory project By NCERT Official

LIST OF INVESTIGATORY PROJECTS BY CBSE

1.To study various factors on which the internal resistance/EMF of a cell depends.

2. To study the variations in current flowing in a circuit containing an LDR because of
a variation in
(a) the power of the incandescent lamp, used to ‘illuminate’ the LDR (keeping
all the lamps at a fixed distance).
(b) the distance of a incandescent lamp (of fixed power) used to ‘illuminate’
the LDR.

3. To find the refractive indices of (a) water (b) oil (transparent) using a plane mirror,
an equiconvex lens (made from a glass of known refractive index) and an
adjustable object needle.

4. To investigate the relation between the ratio of (i) output and input voltage and (ii)
number of turns in the secondary coil and primary coil of a self-designed
transformer.

5. To investigate the dependence of the angle of deviation on the angle of incidence
using a hollow prism filled one by one, with different transparent fluids.

6. To estimate the charge induced on each one of the two identical Styrofoam (or pith)
balls suspended in a vertical plane by making use of Coulomb’s law.

7. To study the factor on which the self-inductance of a coil depends by observing the
effect of this coil, when put in series with a resistor/(bulb) in a circuit fed up by an
A.C. source of adjustable frequency.

8. To study the earth’s magnetic field using a compass needle -bar magnet by plotting
magnetic field lines and tangent galvanometer.
