    In the measurement of a resistance by Wheatstone bridge the known and the unknown resistances are interchanged to neutralise

    A)  end error

    B)  index error

    C)  error due to thermoelectric effect

    D)  random error

    Correct Answer: A

    Solution :

    Resistance of brass strips, used in Wheatstone bridge, is not zero at the ends. Error due to this reason is called end error. To remove this error the known and unknown resistances are interchanged.
