Electricity: Short Circuits & Direct Currents Current ingasesandliquidsgenerally consists of a flow of positive ions in one direction together with a flow of negative ions in the opposite direction. To treat the overall effect of the current, its direction is usually taken to be that of the po...
The main difference between electric current and static electricity is that the electrons or charges flow through the conductor in an electric current. Whereas, in static electricity, the charges are rest and accumulated on the surface of the substance. The electric current is due to the flow ...

Under the influence of heat, water, electricity, and mechanical stresses, the XLPE insulation layer of cables will gradually deteriorate, which will lead to changes in the dielectric properties of the XLPE [2,3]. Among various stress influences, thermal stress is one of the most important ...
They are of key importance in the processes of conversion and use of electricity. For this reason, transformers and their design, properties, and parameters significantly affect the structure and computational complexity of models of power systems and networks [1]. This statement applies to the ...
Our current electricity infrastructure based on an alternating current (AC) grid is not sustainable. Most of our loads today, except a few inductive loads, can operate on direct current (DC) as the input power. Photovoltaics generate DC power, and batteries store DC power. Wind turbines ...
