Displacement current is given by: id=dtdQ=εodtdϕE. According to Maxwell's Ampere circuital Law, the line integral of magnetic field along a closed path is equal to μo times the total current.

Answer: This may help you

Explanation:

In electromagnetism, displacement current density is the quantity ∂D/∂t appearing in Maxwell's equations that is defined in terms of the rate of change of D, the electric displacement field. Displacement current density has the same units as electric current density, and it is a source of the magnetic field just as actual current is. However it is not an electric current of moving charges, but a time-varying electric field. In physical materials (as opposed to vacuum), there is also a contribution from the slight motion of charges bound in atoms, called dielectric polarization.
