Consider the rectangular domain as shown with the applied voltage on the boundary:

Write a Matlab code to find the electric potential V (x, y) and the electric field E(x, y) at all grid points in the domain.

• Draw equipotential lines in the domain.

• Draw contour plot of constant field intensity.

• How much energy is stored in this device?

• Could this device be considered as a capacitor? If so, find its capacitance.

• Disucss anything else about this problem that you find interesting or important.
