                                                               section A

1. To find resistance of a given wire using metre bridge and hence determine the resistivity (specific resistance) of its material.

2. To determine resistance per cm of a given wire by plotting a graph of potential difference versus current.

3. To determine resistance of a galvanometer by half-deflection method and to find its figure of merit.

4.To compare the EMF of two given primary cells using potentiometer.

                                          Section B

1. To determine angle of minimum deviation for a given prism by plotting a graph between angle of incidence and the angle of deviation

2.To determine refractive index of a glass slab using a travelling microscope.

3. To find, the focal length of a convex lens by plotting graphs between u and v or between 1/u and 1/v.

4.To draw the I-V characteristic curve of a p-n junction in forward bias and reverse bias.
