Current density is the amount ofelectric currentthat flows through a unit value of the cross-sectional area.It is a vector quantity comprising both a direction and scalar magnitude. Current Density is measured in terms ofAmpereper square meter (A/m2). In the case of a steady current, the s...

In particular, we find precise conditions under which we can extract the current-current from the density-density correlation functions and vice versa . We use these results to prove a formula relating the density response and the electrical conductivity in strongly disordered systems. We introduce ...
The two-carrier model, the simplest possible approach to explain the temperature and field dependences, is derived from the Tsuji formula by dividing the Fermi surface integral into integrals over two spherical Fermi spheres. In the model, we assume that the two Fermi spheres have different charge...
The relationship between current density (j) andηin OER can be described by the Butler-Volmer equation. When the anodic overpotential is large enough, the formula is as follows (20) j = j0 n F RT whereRis the universal gas constant,Tis the thermodynamic temperature,αais the transfer coeff...
A detailed IEM technique to compute the current distribution over the surface of a rail, current profile around the rail, and maximum current density (J) formula will be presented in this paper. The current distribution is computed for rectangular and circular rails that are shown in color ...
This is the maximum heat utilized by a TC, initially referred to as ‘TC heat potential’, equivalent to OHC, which is computed based on the following formula from ref. 11. $${{{\rm{OHC}}}={{\int }_{\!\!\!-H26}^{0}}Q\left(z\right){dz},\,{{{\rm{with}}}\,Q(z)=\...
They derived an analytical formula for the harmonic Hall voltages and found that the effective fields strongly depend on the thicknesses of Ta and CoFeB layers in Ta/CoFeB/MgO heterostructures. For practical use of the SOT in spintronics devices, it is of great importance to elucidate the ...
We report the determination of critical current density Jncnflowing in YBan2nCun3nOn7-δnsuperconducting thin films by two independent criteria. The estimation of Jncnwas carried out by an inductive technique, i.e., the so-called screening technique. Both the imaginary part of the fundamental ha...
