Displacement current is:

Question

Quizplus · Accepted Answer

Displacement current is given by the equation "dD/dt = ε(dE/dt)", where D is the electric flux density, ε is the permittivity of the medium, and E is the electric field. Rearranging this equation, we can write it as "dE/dt = (dD/dt) / ε". Substitute the value of E in the Maxwell's equation "∇ × H = J + ∂D/∂t" and we get "∇ × H = J + ∂(εE)/∂t + ∂(εU)/∂t", where U is called the electric displacement or polarization. The second term on the right side of the equation is the displacement current. So, the correct choice is B.
