Various embodiments include methods and apparatus structured to balance electrode pairs (112,312) of a tool (100,300) providing volt- age equivalence between the electrode pairs. An electrically conductive wire (113,313) coupling the electrodes of an electrode pair can be arranged such that resistance of the electrically conductive wire does not adversely affect the voltage equivalence. The electrically conductive wire can also be structured to provide temperature independent balancing by arranging the electrically conductive wire with respect to a measuring node (116,316). Additional apparatus, systems, and methods are disclosed. |
