*Overview*

This is a simulation about an electric dipole.

It’s possible to move the two charges ** q_{1}** and

*q*_{2}generating the field and the point

*in which the electric field is measured (click the mouse on them and drag).*

**P**In the point

**are also shown the electric field vectors generated by**

*P**q*and

_{1}*q*, their vectorial sum (that is the total electric field vector in

_{2}*P*) and the field line passing through it (red line).

With the two ** q_{1}** and

*q*_{2}sliders (in the field parameters tab) it’s also possible to change the charge intensities of

*q*

_{1}and

*q*

_{2}and see how the field lines change (especially comparing their configuration when the charges have opposite sign values or when they are equally signed).
