Question

A parallel plate capacitor with plate area A and plate separation d is filed with a dielectric material of dielectric constant K = 4. The thickness of the dielectric material is x, where $x < d$.

Let C1 and C2 be the capacitance of the system for $x=\frac{1}{3d}$ and $x=\frac{2d}{3}$, respectively. If $C_1 = 2μF$, the value of C2 is __________μF.

Answer 1

The value of $C_2$ is 3 μF.
