Electrical Craft Principles
Although the power factor of a motor varies with load, it is usually higher at full
load than at lower loadings. Full-load power factor can be safely used to
calculate the current rating of cables, since the rise in current owing to reducing
power ...

Power Transmission and Distribution
For a given load P, with voltage VL and power factor cos0, the load current is
given by V3FL cos0 From the above expression for a given load it is clear that, if
the power factor is low, the load current will be higher. This leads to the following
...

The Industrial Electronics Handbook
Because active power (or average power, or real power) is proportional to the
cosine of the power factor angle, the reactive power was defined as somewhat of
an opposite phenomenon, namely proportional to the sine of the power factor ...
