Checking myself for accuracy and clarity.

Ignore the low quality MS paint skills. The image title is missing. Title is Ro=Rn+K(W-We) https://imgur.com/a/4SFSAf9 I believe this is a correct representation of the concept but want to double check as I dislike providing inaccurate information to others even by mistake.

Edit. I am gonna go forward with the assumption this is workably accurate unless proven otherwise then.
