Won't the fields tend to cancel out near the center of the spiral?
When you say center, do you mean looking at the top/bottom or at its side? There should be a little dead zone towards the center if looking at the top or bottom of it. I just want to make sure I have the proper dielectric and thickness for what I want to do. I am going to use a 20KHz, fixed frequency, 12,000V, 30 mA neon light power supply. That will be another learning experience because I have never had the need to calculate something like that before. Anyone know anything about dielectric constants of materials and how they are affected by frequency, voltage, and current?Won't the fields tend to cancel out near the center of the spiral?
So you can run any amount of current through a capacitor as long as the voltage remains below breakdown? It seems there must be some upper limit per unit volume of a given material that a capacitor can handle. Or, can a capacitor take all the current you give it as long as you provide an adequate heatsink? The "current" would be proportional to the amount of molecular or atomic electron cloud deformation per unit time and per unit volume and that effect would propogate to the electrons on the other plate as if the dielectric was a wire. Is that right?Dielectrics don't conduct current - until breakdown voltage is exceeded, that is.
I was actually referring to the dielectric and not the plates when I said, "The current would be proportional to the amount of molecular or atomic electron cloud deformation per unit time and per unit volume and that effect would propogate to the electrons on the other plate as if the dielectric was a wire."Side note: other than inclusions and impurities, there are no molecules in metal.
