6 FAQs about [The difference between the thickness of iron shell capacitors]
Why does the thickness of plates affect the capacitance of a capacitor?
As I understand it, this is because if the plates are larger, then for a given potential difference between the plates more electrons can be pushed onto the negative plate by the cell. My question is, then by the same (and I am guessing flawed) logic, why does the thickness of the plates not affect the capacitance of the capacitor?
How thick should a metal film capacitor be?
Think of metal film capacitors which literally have a metal film vapor deposited onto the dielectric. The less metal thickness the less the waste in mass and bulk and metal. It only needs to be thick enough to have full conductivity. Adding thickness just adds mass and bulk with no gain, so optimal thickness is to be as thin as possible.
Does dielectric thickness affect capacitance?
What does affect capacitance is the thickness of the dielectric, so the thinner the better, but it must be thick enough to block/handle the rated voltage. More metal (and dielectric) in terms of windings also increases capacitance. I am sure you have noticed that for a given voltage, more capacitance means a larger capacitor.
What is a spherical capacitor filled with dielectrics?
Figure 5.10.4 Spherical capacitor filled with dielectrics. The system can be treated as two capacitors connected in series, since the total potential difference across the capacitors is the sum of potential differences across individual capacitors. The equivalent capacitance for a spherical capacitor of inner radius 1r and outer radius r
How does dielectric strength affect a capacitor?
The relative permittivity or dielectric constant of a capacitor affects the maximum value of capacitance achievable for a given plate area and dielectric thickness. The dielectric strength is a rating of the dielectric’s resistance to voltage breakdown as a function of its thickness.
What happens when a capacitor has a capacitance 0?
To see how this happens, suppose a capacitor has a capacitance C 0 when there is no material between the plates. When a dielectric material is inserted to completely fill the space between the plates, the capacitance increases to is called the dielectric constant.
