the questions and graph is at the end of the pdf file. others are instructions.

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.
