Geometrically and electrically accurate finite element models of microelectrodes used in microstimulation of the central nervous system were created to examine the current density along the surface of the electrode as well as the electric field generated within the tissue medium. Sharp tipped ...
In 1963 Ridley postulated that under certain bias conditions circuit elements exhibiting a current- or voltage-controlled negative differential resistance will separate into coexisting domains with different current densities or electric fields, respecti
To solve the problem, we need to find the resistivity (ρ) and conductivity (σ) of the material given the current density (J) and electric field (E).Step 1: Convert the given values to SI units - Current density (J) = 10 A/cm
The concept of current density is very simple but it is much use full in the field of electrical engineering. Current Density in Metal Imagine a conductor with a cross-section of 2.5 square mm. If an electric potential causes a current of 3 A, the curren

来定义一下电流密度 Electric Current Density 吧,电流密度就是单位面积内的电流量 \vec{j}(\vec{r})=\frac{\vec{I}}{A} ,单位是安培除以米的平方 \frac{A}{m^2} 。这些单位其实都是用公式导出的,公式怎么计算,单位也就怎么计算。 我们知道电流是电荷量对时间的微分,也就是说 j(\vec{r})=\frac{...
The electriccurrent densityvector field also satisfies superposition principle, some applications thereof are introduced. 摘要电流密度矢量场也满足叠加原理, 给出了一些应用电流密度场叠加原理的例子. 互联网 We shall use the microscopic analysis technique to investigate thecurrent densitydistribution. ...

By researching the mechanism and functions of current density's radial distribution along the conductor in constant current field and Hall electric field's production,the consequence shows that the velocity of current carriers in orientation movement increases with the growth of the density of radial ...
Clear increases of the vertical electric field and current density were observed across over the Honsyu Island with a balloon-born electric field/current antenna at the approximately constant altitude of about 26 km in the stratosphere. The increased rate amounts to 50% over the land of about ...
