니 4. (15 points) Mica has a dielectric constant of x = 6.0, a dielectric strength of 39.4x10 V/m, and it natural flakes into sheets between 0.18 mm and 16 mm thick. a. (7 points) How would you design a 376 pF (pico = 10-¹2) capacitor using mica as the dielectric. (Give the actual shape and size you would use.) → C = K C₂ where C = 376 PF and I 6.0 ↳ with Dielectric Lo Dielectrics get more polarized, putting More negative un positive plate, and more positive on negative plak.
