Homework Statement
A parallel plate capacitor has a capacitance C when there is no dielectric inside of it. Suppose a wedge
of material with dielectric constant K is inserted in between the plates of the capacitor (see figure). The
bottom face of the wedge has the same area as the plate of the capacitor. The height of the wedge is
equal to the thickness of the capacitor, t on the left edge and varies linearly until the height is zero on
the right edge. What is the new capacitance with this dielectric inserted?
HINT: See if you can split up the capacitor into small capacitors that each have a dielectric in them that
you know how to deal with.
Homework Equations
C = KC0
C = εA/d
The Attempt at a Solution
Well, I first started with slicing the capacitor vertically into n small slices and from here to set up an integral, but I'm not sure how to set up the integral...
