    Let \[{{n}_{p}}\] and \[{{n}_{e}}\] be the number of holes and conduction electrons in an intrinsic semiconductor. Then

    A) \[{{n}_{p}}>{{n}_{e}}.\]        

    B)        \[{{n}_{p}}={{n}_{e}}.\]

    C) \[{{n}_{p}}<{{n}_{e}}.\]        

    D)        None of these

    Correct Answer: B

    Solution :

    [b] In intrinsic semi-conductor, the number of holes are equal to number of electrons i.e.,\[{{n}_{p}}={{n}_{e}}\]
