QR code


2D illustration of the link between electric field and electric potential. The grad(V) vector is computed at every point of a geometric matrix the interval values of which you can modify.

Click on the circles at lower right to select the interval to be used.

Drag the sliders to select the charge values

Learning goals

  • To study the link between the electric field (vectorial value) and the electric potential (scalar value).
  • To illustrate the 2D meaning of the gradient operator.
