What is the capacitance of a capacitor with a dielectric?

Therefore, we find that the capacitance of the capacitor with a dielectric is C = Q0 V = Q0 V0 / κ = κQ0 V0 = κC0. This equation tells us that the capacitance C0 of an empty (vacuum) capacitor can be increased by a factor of κ when we insert a dielectric material to completely fill the space between its plates.

Can a dielectric be used in a capacitor?

There is another benefit to using a dielectric in a capacitor. Depending on the material used, the capacitance is greater than that given by the equation C = εA d C = ε A d by a factor κ κ, called the dielectric constant.

What is the dielectric constant of a nylon capacitor?

Because the capacitor plates are in contact with the dielectric, we know that the spacing between the capacitor plates is d = 0.010 mm = 1.0 × 10−5m d = 0.010 mm = 1.0 × 10 −5 m . From the previous table, the dielectric constant of nylon is κ = 3.4 κ = 3.4 . We can now use the equation C = κε0 A d C = κ ε 0 A d to find the area A of the capacitor.

How does a capacitor affect a dielectric field?
