Confusing with this text... Pls help

[powersys]

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

Do you think the following statements are OK?

... 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.

Shoud 'lagging' read as 'leading'? Pls advise.

I think fig3-10 and 3-14 should say leading and fig3-15 lagging
