I would like to calculate theoretically the capacitance of a bearing with metallic rings and ceramic spheres (see http://en.wikipedia.org/wiki/Rolling-element_bearing.
The expression for a cylindrical capacitor is: (2*pi*eps0*l)/(lnb/a).
However, when adding some spherical balls inside the...
I mean if it becomes conductive at AC.
Simplifying, the question would be... is is possible to apply a low frequency signal to a dielectric material and not to be conductive, but when increasing the frequency to become conductive?
Dear colleagues,
I have a question related with dielectrics and their conductivity when High Frequency signals are applied.
Is it possible to become conductive a dielectric material if sufficiently High Frequency signals are applied?
When a high frequency signal is applied to a...
