Answer to Question #320906 in Electricity and Magnetism for ukiskinis

Question

Suppose the space between the plates of the capacitor is filled

with equal thickness of the same dielectrics but arranged as

shown in the figure. Each having an area of 8.0x10-4 m2 and

separated from each other by 5.0 mm. Half of the space between

the plates is filled with glass and the other with mica. What is its

capacitance?

Answer 1

$C=\frac{\varepsilon_0(\varepsilon_1+\varepsilon_2)S}{2d}=5.7~pF.$
