Space charge and DC electric field characteristics have been investigated on medium voltage size models of cable joints composed of cross-linked polyethylene (XLPE) and ethylene-propylene rubber (EPR). The joint models were constructed in such a way that the dielectric interface between XLPE and EPR...
He has a Masters in Education, and a Bachelors in Physics. Cite this lesson Electric fields and motion of charges have two distinct definitions and it's important to not confuse them. Clarify what an electric field is, discover how it's related to motion, and learn the main electric ...

The number and the spin angular momentum of electrons on each site, and the charge and the spin currents between adjacent sites are theoretically studied. Considering one dimensional electronic system including impurity atoms with some density, the static electric field (represented by an electric pote...
