Field and potential in parallel plate capacitor. Consider Figure 6.51. Using the triangular shape functions defined in Section 6.5.1 and the implementation in Section 6.5.2:
(a) Calculate the potential distribution inside the capacitor.
(b) From the potential distribution, calculate the electric field intensity in the capacitor. Sketch the solutions.
(c) Find the analytic solution and compare with (a) and (b).
