Electric Field Potentials

This is a Java applet.

Be sure to wait until the applets have loaded, then press Start. When the field is displayed, then you can try the potentials.

Potential A Potential B Potential C Potential D

Description

The panel on the left displays an electric field plot. The arrows in the field plot represent the direction of the electric field and the colours represent the magnitude of the electric field.

Procedure:

  • Draw equipotential lines in the electric field (in the left panel) by double-clicking at a position.
  • After you have drawn a number of equipotential contour lines, load each of the potential plots below (to be displayed in the right panel).

Which of the potential plots best corresponds to the electric field?
