  • question_answer
    Minimum number of capacitors each of \[8\,\mu F\]and 250 V used to make a composite capacitor of \[16\,\mu F\]and 1000 V are:

    A) 8                     

    B) 32       

    C) 16                                

    D) 24

    Correct Answer: B

    Solution :

    (b) 32 Minimum number of capacitors in each row \[=\frac{1000}{250}=4\] Therefore, 4 capacitors connected in series. If there are m such rows, then total capacity \[=m\times 2=16\] \[\therefore \,\]Minimum number of capacitors \[=4\times 8=32\]
