,Neuere Ausführungen von Fahrtreppen,eveloped for the representation of phase difference. If we take phasor OA of length . in figure 7.1. and turn it through 90° in an ., we say that we have . the phasor. To indicate that the phasor has rotated through 90°, we write.where j is the . Length OB is shown in bold type to indicate that it is a phasor quantity.

Grundlagen des Bauingenieurwesens system (figure 8.1a) the phase difference is 90°, and in the three-phase system (figure 8.1b) it is 120°. Although the three-phase system is the most popular, some installations use six-, twelve- and twenty-four-phase systems.

Electrostatics,e manner of figure 4.1a. The electric field is represented by imaginary lines, each of which shows the path that would be traced out by the movement of a free electric charge. The . at any point is given by the direction of the force experienced by a unit positive charge placed at that point.
