Volume between capacitor

Student 1056 9 years ago updated by Physics Tutorial Center Staff 9 years ago 1

A large capacitance of 1.10 mF is needed for a certain application.

(a) Calculate the area the parallel plates of such a capacitor must have if they are separated by 4.77 µm of Teflon, which has a dielectric constant of 2.1.
282.32 m2

(b) What is the maximum voltage that can be applied if the dielectric strength for Teflon is
60 ✕ 106 V/m

286.2 V

(c) Find the maximum charge that can be stored.
.31482 C

(d) Calculate the volume of Teflon alone in the capacitor.

The Teflon occupies the space between the two plates. m3

If I am reading your post correctly you have correctly solved the first three parts of the question and you are stuck on part (d) to find the volume between the plates of the capacitor.


You know the area of the plates as found in part (a) so now you need to calculate the separation of the plates to be able to find the volume. Try to find an equation in your notes or you textbook that relates capacitace, area of the plates, and distance between the plates. If you are still stuck after this reply to this post again and we can dig a little deeper into this problem.
