Homework Statement



A capacitor is formed by 2 square metal plates of edge a and separated by distance d. Dielectrics of dielectrics constants K1 and K2 are filled in the gap as shown.

2. The attempt at a solution

This was my initial approach:

I integrated the parallel combination of elemental capacitors dC1 and dC2, but I didnt get the correct answer.

Next, I tried taking the elemental capacitors in series instead of parallel:

This time my answer turned out to be correct.:smile:

Can someone help me identify the flaw in my initial approach? I suspect I was wrong in assuming that the elemental capacitors were in parallel in the first place.

Opinions?
