Question

wnen two parallel metal plates whichare each A mit 2in rea and d units apart is given by EA where ε is a constant called the permittivity of the material between the plates (which you can leave as a constant). Consider two circular plates, each having a radius of 3 cm. The first plate lies on the plane x +2y+3z 4 and the second plate lies on c +2y+3z-6. Find the capacitance between the plates.

Answer 1

C = A epsilon_0/d Area (A) = pi r^2 = pi times 9 times 10^-4 m^2 A = 2.83 times 10^-3 m^2 epsilon_0 = 8.85 times 10^-12 d = 2 m/squareroot 14 (distance between both plane) c = 2.83 times 10^-3 times 8.85 times 10^-12 /(2/squareroot 14) C = 4.685 times 10^-14 F
