On this page (https://www.allaboutcircuits.com/te...ent/chpt-11/true-reactive-and-apparent-power/), in the box summarizing apparent power formulas, the second formula is listed as Q=E^2/Z, but it should be S=E^2/Z.

Could this get fixed? I use this book for my class, and a few students mistakenly used this formula/were confused!

Hi,

Thanks for bringing this to our attention. We have corrected the error you found. While we were at it, we also replaced E with V for voltage to match standard electrical engineering.

We would love to hear where you are using this for a class textbook! Glad that you find it a useful resource.

Best,

Dale Wilson

 

Thanks so much! I have been using it for my Analog Circuits class at Clackamas Community College for non-majors (for mechanical/industrial/chemical engineers, etc).
