Alright fellas,
We all know that the resistance of R2 is (should be) 1.67 times that of R1 (or Rn) on rings. We also know that adding R1 to R2 gives us (...Wait for it...) R1+ R2. Nowt new here yet.
But...
Do you know how to reverse it. i.e. Calculating R1 and R2 from R1 + R2?
If you do 'R1+R2' * 1.4981273408 you will get R1. Then obviously back to R1 * 1.67 for R2.
There you, has its uses.
