Question

what is displacement density

Answer 1

In short, this is simply the time rate of change of theElectric Flux Density. That is, this quantity is a measure of how quickly the D field changes if we observe it as a function of time. This is different than if we look at how the D field changes spatially - i.e. over a region of space for a fixed amount of time.

This term is known as the Displacement Current Density.

It symbolizes the type of electric current that flows through a capacitor. Displacement current is different than the current that flows through a wire or an inductor - this is carried by free electrons on a conductor, and is known as conductive current.

We know that in some sense current flows through a capacitor, but there is no physical conductive connection between the parallel plates of a capacitor. And to ensure current flowing in a circuit or loop remains constant, we need this term.

This was actually introduced to Ampere's Law by Mr. Maxwell himself, which was a stroke of genius that laid the theoretical basis for wave propagation, amongst other things

Answer 2

The water displacement method is an effective technique for finding the volume of an insoluble, irregular solid and its subsequent density.
