****Please make it sure that it explains with logic and/or writing. It is an essay but it has to be one based on scientific facts. Please be specific preferably with equations and/or calculations (such as short derivations) if necessary to make the argument. The suggested length is between 400-500 words.

A) What are the Maxwell's Equations and their significance in physics?

B) What is the Displacement Current and its meaning?

Thank you for your help!

Expert Solution

displacement current density is the quantity ∂D/∂t appearing in Maxwells equations that is defined in terms of the rate of change of D, the electric dispalcement field. Displacement current density has the same units as electric current density, and it is a source of the magnetic 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 dilectric polarisation.
