Find the capacitance of a parallel plate capacitor having plates of area 3,95 m2

Question

Find the capacitance of a parallel plate capacitor having plates of area 3,95 m2 that are separated by 0.690 mm of Tefion. The dielectric constant of Teflon is 2.1. How is capacitance related to plate area and separation for a parallel plate capacitor? Did you consider the effect of the dielectric? uF Additional Materials Reading My Notes O Ask Your Teacher 16 19.5.WA.045 2. A large capacitance of 1.24 mF is needed for a certain application l plates of such a capacitor must have if they are separated by 4.79 um of Tefion, which has a dielectric constant of 2.1 (b) What is the maximum voltage that can be applied if the dielectric strength for Tefion is 60 x 106 v/m (c) Find the maximum charge that can be stored. (d) Calculate the volume of Teflon alone in the capacitor m3 itional Materials 0:10 PM

Explanation / Answer

1)

Capacitance, C = k e0 A/d

C = (2.1 x (8.854 x 10^-12) x 3.95)/(0.690 x 10^-3)

C = 1.06 x 10^-7 F = 0.106 uF
