A parallel plate condenser is filled with two dielectrics as shown in figure. Area of each pate is $A m^{2}$ and the separation is $d$ metre. The dielectric constants are $K_{1}$ and $K_{2}$ respectively. Its capacitance in farad will be

Options:

Answer:

Solution:

From the formula $C = \frac{ε _{0} A}{\frac{1}{k _{1}} + \frac{1}{k _{2}}} = \frac{ε _{0} A}{t} (\frac{k _{1} k _{2}}{k _{1} + k _{2}}) = \frac{2 ε _{0} A}{d} (\frac{k _{1} k _{2}}{k _{1} + k _{2}})$
