Silver Plated Tungsten and Tungsten-Rhenium Probe Needles

Material DC Resistivity

Note: The resistance values were calculated using Ohm’s Law for parallel resistors.  There was a statistically significant correlation between the “theoretical values” in the table and direct measurements from the various probe needle diameters.
