SUBJECT: Line Integrals
DESCRIPTION: This applet illustrates the concept of line integrals. By selecting a line type and manipulating the source charge, you can see the effect on the line integral of dot product of the field and line element for the various configurations. The blue arrows represent the direction of the line elements and the red arrows represent the electric field at that line element. The line types are circular, rectangular, and random.
