    In Meter bridge or Wheatstone bridge for measurement of resistance, the known and the unknown resistances are interchanged. The error so removed is

    A)  end correction

    B)  index errror

    C)  due to temperature effect

    D)  random error  

    Correct Answer: A

    Solution :

    In Meter bridge experiment, it is assumed that the resistance of the L shaped plate is negligible, but actually it is not so. The error created due to this is called end error. To remove this the resistance box and the unknown resistance must be interchanged and then the mean reading must be taken.
