An orthogonal coordinate system in which a continuous two-dimensional charge distribution is drawn with surface charge density $$\sigma(\boldsymbol{r})$$. The position vector $$\boldsymbol{r}$$ goes from the origin to the location inside the charge distribution within the surface $$A$$.

The field position vector $$\boldsymbol{R}$$ goes to a field point where the electric field caused by the charge distribution is to be calculated.

Die Verbindungenvektoren $$\boldsymbol{R} - \boldsymbol{r}$$ geht dabei von einem Punkt innerhalb der Ladungsverteilung zum betrachteten Feldpunkt. Dieser Verbindungsvektor ist wichtig für die Berechnung des elektrisches Feldes.
