    CAPACITANCE CALCULUS OF A BEARING

    I would like to calculate theoretically the capacitance of a bearing with metallic rings and ceramic spheres (see http://www.alibaba.com/catalog/10516334/Ceramic_Bearing_Balls.html). The expression for a cylindrical capacitor is: (2*pi*eps0*l)/(lnb/a). However, when adding some spherical balls...

    Dielectric material becomes conductive at High Frequency?

    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 dielectric...
