1) The plates of a parallel-plate capacitor in vacuum are 3.50mm apart and 2.75m in area. When you apply a certain potential difference across the capacitor, the surface charge density on the positive plate is 1.4010-5C/m. a. (10 pts) Calculate the capacitance of the capacitor. b. (10 pts) Find the potential difference. 1.40x10 Name PHYS 2200-01 Fall 2023 Exam 2 v01 7 of 24 2) In (Figure 1), C = Cs = 9.40F and C2 = C3 = C4 = 5.30F. The applied potential is Vab = 220V. C. a. (20 pts) What is the equivalent capacitance of the network between points a and b? Making a sketch for each step is EXTREMELY helpful!! b. (10 pts) Calculate the charge on capacitor C1.
