Using the principle of Wheatstone Bridge, describe the method to determine the specific resistance of a wire in the laboratory. Draw the circuit diagram and write the formula used. Write any two important precautions you would observe while performing the experiment.
Draw a labelled circuit diagram of a simple electric motor and explain its working. In what way these simple electric motors are different from commercial motors?
A beam of white light is incident normally on the surface AB of an equilateral prism ABC and emerges out of it suffering a deviation of 60^(@) . (a) Draw a diagram to show the path of beam till it emerges out of the prism. Mark the angles wherever necessary. (b) What assumption have you made while drawing the diagram ? (c) Name the phenomenon exhibited by the light beam.
