20 : 10 : 39 : 33 . Source resistance calculation. The source resistance is calculated for each cow contact location measured and the value recorded on the cow contact test form on file with the commission. The following formulas are used to calculate source resistance:

1. (1) Rsource = Rshunt x ((Voc-Vshunt) / Vshunt; and
2. (2) Rsource = Voc/Ishunt - Rshunt.
