  • question_answer Two parallel plate of area A are separated by two different dielectrics as shown in figure. The net capacitance is-

    A) \[\frac{4{{\varepsilon }_{0}}A}{3d}\]

    B)               \[\frac{3{{\varepsilon }_{0}}A}{4d}\]

    C) \[\frac{2{{\varepsilon }_{0}}A}{d}\]                  

    D) \[\frac{{{\varepsilon }_{0}}A}{d}\]

    Correct Answer: A

    Solution :

    \[{{C}_{0}}\,=\,\frac{{{\in }_{0}}A}{d}\] \[{{C}_{1}}={{K}_{1}}\times 2{{C}_{0}}\text{ }\,\,2{{C}_{0}}{{K}_{2}}={{C}_{2}}\]
