Tensors in Physics

Electric Field and Electric Current

[/latex]\begin{bmatrix} a & 0 & 0 \\ 0 & b & 0 \\ 0 & 0 & 0 \end{bmatrix} E = J

Because of the structure of the material, there is insulation against current flow in the z-direction.

The conductivity tensor operating on E gives us J.

  • E- Electric Field
  • J- Electric Current
