Question

47. A parallel-plate capacitor with no dielectric has
capacitance of 0.5 uF. The space between the plates
is then filled with equal amounts of two dielectrics of
dielectric constants 2 and 3 in the two arrangements
as shown one by one. Find the ratio of capacitances
and CII
​

Answer 1

Answer:

Explanation:

Assume the capacitor in the first diagram equivalent to two parallel capacitors and find the equivalent capacitance.

Similarly, assume the capacitor in the second diagram equivalent to two capacitors connected in series, and then find the equivalent capacitance.
