List of investigatory projects
Class ----12
1- To study various factors on which internal resistance /EMF of a cell depends.
2- To investigate the relation between the ratio of
1-Input and output voltage and
2-Numbers turns in the secondary coil and primary coil of a self-designed transformer.
3-To set up a common base transistor circuit and to study its
and to calculate its current gain.
input and output characteristics
4-To set up a common emitter transistor circuit and to study its input and output characteristics and
to calculate its current gain.
5-To construct a switch using a transistor and to draw the graph between the input and output voltage
and make the cut –off , saturation and active region .
6-Using appropriate focal length lenses obtain magnifying power of compound microscope from
collection various lenses and compare magnifying power also tell which one is more suitable?
7-Using appropriate focal length lenses obtain magnifying power of astronomical telescope from
collection of various lenses and compare magnifying power also and tell which one is more suitable?
8- To study the factors on which self-inductance of a coil depends by observing the effect of this coil,
when put in a series with a resistor/bulb in a circuit fed up by an A.C.source of adjustable frequency.
9- To investigate the dependency of the angle of deviation on the angle of incidence using a hollow
prism filled one by one with different transparent fluid.
10-To discuss production of E.M .waves produced by different method .How these waves are helpful in
communication. Discuss in detail .Compare their properties and application.
11-To design an appropriate logic gate combination for a given truth table.
12-To discuss report of effect of dielectric plate on 1-capacitance 2- charge 3- potential difference
