CBSE Class 12 Physics Practical Syllabus


  1. To determine resistance per cm of a given wire by plotting a graph for potential difference versus current.
  2. To find resistance of a given wire using metre bridge and hence determine the resistivity (specific resistance) of its material.
  3. To verify the laws of combination (series) of resistances using a metre bridge.
    To verify the laws of combination (parallel) of resistances using a metre bridge.
  4. To compare the EMF of two given primary cells using potentiometer.
  5. To determine the internal resistance of given primary cell using potentiometer.
  6. To determine the resistance of a galvanometer by half-deflection method and to find its figure of merit.
  7. To convert the given galvanometer (of known resistance and figure of merit) into a voltmeter of desired range and to verify the same.
    To convert the given galvanometer (of known resistance and figure of merit) into an ammeter of desired range and to verify the same.
  8. To find the frequency of AC mains with a sonometer.


  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 1/u and 1/v.
  4. To find the focal length of a concave lens, using a convex lens.
  5. To determine the angle of minimum deviation for a given prism by plotting a graph between angle of incidence and angle of deviation.
