The electric flux density D = ϵ E, having units of C/m 2, is a description of the electric field in terms of flux, as opposed to force or change in electric potential. It may appear that D is redundant information given E and ϵ, but this is true only in homogeneous media. The concept of electric flux density becomes ...

A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube.
