A parallel plate capacitor having plates of area S and plate separation d, has capacitance C1 in air. When two dielectrics of different relative permittivities ( ε1=2 and ε2=4) are introduced between the two plates as shown in the figure, the capacitance becomes C2. the ratio C2/C1 is
The Attempt at a Solution
if we name the components 1,2,3,4 in clockwise manner,in the solution 1 and 2 are taken in series and 3 and 4 are taken in series and they both are connected parallel,can we also take 1 and 4 in parallel and 2 and 3 in parallel and they both are connected in series?in that case answer comes out to be 12/5 where have i gone wrong?
