In this Part 1 of this series of articles, the accuracy on the obtention of the shunt resistance (R

) is investigated theoretically, as function of the number of measured points per voltage (

) and percentage noise (

). Reasonable values are obtained for R

, R

, and I

, with
P
V
= 11 measurement points per V if the
p

is 0.1% or less. For a reasonable determination of n at least
P
V
= 101 measurement points per V are needed. I

determination requires
p
n
of 0.01% or lower with at least
P
V
= 101 measured points per V and should be evaluated at large values of V. The results given in this Part 1 are used in Part 2 to discuss the reported application of the
