By should be replaced with be in the second sentence of the final paragraph of "Volume 2 AC: Complex Numbers: More on AC ' 'polarity"."

 

See: http://www.allaboutcircuits.com/vol_2/chpt_2/7.html

You are correct. Thanks for taking time to give us some feedback.

Can I also suggest from this page that the title be changed to correct the erroneous speech-marks, i.e. Change Volume 2 AC: Complex Numbers: More on AC ' 'polarity" To Volume 2 AC: Complex Numbers: More on AC "polarity" Or Volume 2 AC: Complex Numbers: More on AC polarity
