Displacement Current

The modified or generalization of Ampere’s law written as

\mathbf{\oint \vec{B}.\vec{dr} = \mu _{0}I + \mu _{0} \varepsilon _{0}\frac{d\phi _{e}}{dt}}

The term \mathbf{\varepsilon _{0}\frac{d\phi _{e}}{dt}} has a dimension of current called displacement current.

\mathbf{I_{d} = \varepsilon _{0}\frac{d\phi _{e}}{dt}}

 

 

\mathbf{I_{d} \propto \frac{d\phi _{e}}{dt}}

from above, the electric displacement current Id through a surface S is proportional to the rate of change of the electric flux \mathbf{\frac{d\phi _{e}}{dt}} through S.
