Physics Investigatory Project Ideas

The document outlines 9 potential investigatory projects for students to work on. Project topics include studying how internal resistance of a cell depends on various factors, how the electromotive force of a cell depends on different factors, how current in a circuit containing a light dependent resistor varies with the power or distance of an illuminating incandescent lamp, determining the refractive index of liquids using lenses and mirrors, investigating the relationship between voltage and number of turns in primary and secondary coils of a transformer, examining how angle of deviation depends on angle of incidence using a hollow prism filled with fluids, exploring how self-inductance of a coil depends on various factors using direct current and alternating current, and studying the Earth's magnetic field using

depends. (Roll no 1 to 4)

2. To study various factors on which the EMF of a cell depends. (Roll no 5


to 8)

3. To study the variations in current flowing in a circuit containing an LDR


because of a variation in - the power of the incandescent lamp, used to
'illuminate' the LDR (keeping all the lamps at a fixed distance). (Roll no
9 to 12)

4. To study the variations in current flowing in a circuit containing an LDR


because of a variation in - the distance of a incandescent lamp (of fixed
power) used to 'illuminate' the LDR. (Roll no 13 to 16)

plane mirror, an equiconvex lens (made from a glass of known refractive
index) and an adjustable object needle. (Roll no 17 to 20)

incidence using a hollow prism filled one by one, with different
transparent fluids. (Roll no 25 to 28)

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. (Roll no 29
to 32)
