Table 3.

Coefficients for the fitted power law equation, 1000/κ = A*|x|^p+y⁰, for the three common diameters of commercially available carbon fibers. The variable `x' is the length of the microelectrode in micrometers. The value for y⁰ was set to the value of (1/κ)*1,000 for a disc microelectrode of the given diameter. The units of 1000/κ are cm.
