A) \[{{\varepsilon }_{0}}A/\left( \frac{{{t}_{1}}}{{{K}_{1}}}+\frac{{{t}_{2}}}{{{K}_{2}}} \right)\]
B) \[{{\varepsilon }_{0}}A/\left( \frac{{{K}_{1}}}{{{K}_{2}}}+\frac{{{K}_{2}}}{{{t}_{2}}} \right)\]
C) \[{{\varepsilon }_{0}}A/\left( \frac{{{t}_{1}}}{{{K}_{2}}}+\frac{{{t}_{2}}}{{{K}_{1}}} \right)\]
D) \[{{\varepsilon }_{0}}A/\left( \frac{{{K}_{2}}}{{{t}_{1}}}+\frac{{{K}_{1}}}{{{t}_{2}}} \right)\]
Correct Answer: A
Solution :
For two mediums of different thickness \[{{t}_{1}},{{t}_{2}}\]capacitance \[C=\frac{{{\varepsilon }_{0}}A}{\left( \frac{{{t}_{1}}}{{{K}_{1}}}+\frac{{{t}_{2}}}{{{K}_{2}}} \right)}\]You need to login to perform this action.
