6.1 Phasor diagram
The phasor diagram shows the fundamental components of the voltages and currents
in relation to each other. The voltages and currents that belong together are depicted
in similar colours (light blue and dark blue, light green and dark green, red and orange).
In this way, the phase angles between the sinusoidal curves can easily be assigned. The
currents are depicted within the inner circle while the voltages are shown in the outer
circle.
