The source current, a fixed constant current, supplied to
an RTD resistive element is called the excitation current.

The excitation current through the RTD's resistive element
the copper lead wire develops a voltage drop.

The voltage drop across the third wire in a 3 wire RTD is
subtracted from the combined voltage drop of the RTD
element and the 2nd wire, which eliminates the voltage drop
of the copper wire and leaving only the voltage drop across
the RTD element.
