Class XII Science

EXPERIMENTS:

SECTION-A​
  1. To find resistance of a given wire using meter bridge and hence determine the 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 verify the laws of series combination of resistances using a meter bridge.
  4. To verify the laws of parallel combination of resistances using a meter bridge.
  5. To determine resistance of a galvanometer by half-deflection method and to find its
    figure of merit.
  6. To convert a given galvanometer (of known resistance and figure of merit) into an
    ammeter and volmeter of desired range and to verify the same.
  7. To find the frequency of the a.c. mains with a sonometer.
SECTION-B
  1. To find the value of v for different values of u in case of a concave mirror and to find
    the focal length.
  2. To find the focal length of a convex mirror, using a convex lens.
  3. To find the focal length of a convex lens by plotting graphs between u and v or between
    I/u and I/v.
  4. To find the focal length of a concave lens, using a convex lens.
  5. To determine angle of minimum deviations for a given prisms by plotting a graph
    between the angle of incidence and the angle of deviation.
  6. To determine refractive index of a glass slab using a travelling microscope.
  7. To find refractive index of a liquid by using
    (i) Concave mirror, (ii) Convex lens and plane mirror.
  8. To draw the I-V characteristic curve of a p-n junction in forward bias and reverse bias.
