Neglecting the fringing fields, find the per unit length capacitance of the two capacitors shown in Figure 3. Assume d = 0.1 mm, w = 8 mm, and , = 3. In both capacitors, half of the volume is filled with a dielectric whose relative permittivity is r. EEO W (a) EO d W E+50 d (b) Figure 3: 2-D Cross-section of two parallel-plate capacitors.
