    A parallel plate capacitor is made by stacking n equally spaced plates connected alternatively. If the capacitance between any two adjacent plates is C, then the resultant capacitance is

    A)  (n - 1)C   

    B)                        (n + 1)C              

    C)        C                           

    D)        n C

    Correct Answer: A

    Solution :

    Each plate is taking part in the formation of two capacitors except the plates at the ends. These capacitors are in parallel and n plates form \[\mu F\]capacitors. Thus, equivalent capacitance between A and \[(h=6.6\times {{10}^{-34}}J-s1cal=4.2J)\]
