Homework Statement


A capacitor consisting of two parallel plates of area A = 7.3 m2 and spacing d = 0.150 m is filled with two parallel slabs of dielectric material of equal thickness and with dielectric constants 1 = 3.20 and 2 = 7.50, respectively. What is the total capacitance?

k1 fills the top half, k2 fills the bottom half. each are d/2 thick


Homework Equations


C=Ae0k / d


The Attempt at a Solution


I tried to find the length of the capacitor using A=length*d so the length would be A/d
and used that for A in the equation. I think I should be using C= C1 + C2 so both equations are the same except different k's
not sure if this is the right approach. i also used d as d/2 for each individual dielectric
