A scaling formula of critical current density for anisotropic superconductors has been introduced on the basis of anisotropic Ginzburg - Landau theory and the classical Kramer scaling law. The model predicts the functional dependence of the critical current density 0022-3727/29/9/036/img7 on ...
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...
and electric current are taken as three base dimensions, and meter, kilogram, second, ampere, kelvin, mole, and candela are the fundamental units. The dimensional formula of individual quantities is used to establish a relationship between them in any dimensional equation. An example of a dimensio...

To find ampere using a voltameter, first find the surface area of the electrode. Make sure to multiply by 2 to include both sides of the plate. Then multiply that by the current density to get the number of amperes. the formula is A x J = I where A is total surface area, J is ...
The devices employed 470-nm-wide AlGaInAsSb waveguide optimized for improved device differential gain. CW threshold current density about 100 A/cmper QW and slope efficiency of 150 mW/A were demonstrated at 16degC.关键词: III-V semiconductors aluminium compounds current density gallium arsenide ...
Another mode in dynamical friction: why does a constant density structure suppress dynamical friction? Dynamical friction is a fundamental and important phenomenon in astrophysics. The Chandrasekhar formula is a well-known analytical estimation of the effect. However, current astrophysicists have realized ...
The resistivity of a material is defined in terms of the magnitude of the electric field across it that gives a certain current density. It is possible to devise an electrical resistivity formula. ρ Where: ρ is the resistivity of the material in ohm metres, Ω⋅m ...
