We know that:
Lagging power factor means that current lags voltage, implying an inductive load.
Leading power factor means that current leads voltage, implying a capacitive load.
An inductive load is represented by R + jX
An capacitive load is represented by R - jX
The attached text was copied from a textbook. Do you think there are mistakes in the text and figures?
For example:
... line-5 of paragraph P1
For a load of capacitor VAr is produced and considered negative or lagging as in Figure 3.10.
... line-2 of paragraph P2
A capacitive load on the other hand will be represented by R-jX as shown in Figure 3.12 and hence produces lagging VArs.
Pls check if there are other mistakes.
Please advise. I'm confused now....
Thanks
