    Flux, another type of line integral in the plane, is discussed in this lecture. Flux is described as measuring how much fluid passes through a curve C per unit time in a velocity field. Green’s Theorem also has something to say about flux, and this is explained in this lecture as well. Divergence, what it means, what it measures, and its geometrical interpretation are also explained.
