  • question_answer
    A parallel plate air capacitor has a capacitance of \[100\mu F.\]The plates are at a distance d apart. If a slab of thickness t(t<d) and dielectric constant 5 is introduced between the parallel plates, then the capacitance will be 

    A) \[50\mu F\]

    B) \[100\mu F\]

    C) \[200\mu F\]

    D) \[500\mu F\]

    Correct Answer: C

    Solution :

    [c] Capacitance will increase but not 5 times (Because dielectric is not filled completely). Hence, new capacitance maybe \[200\mu F\],
