Abstract :
Coaxial straight-wire resistance standards with calculable frequency dependence have been used to tie alternating-current (AC) measurements to direct-current (DC) measurements of resistance. Coaxial standards of values 100 /spl Omega/ and 1000 /spl Omega/ are compared with each other and with other resistance standards at several frequencies up to 15920 Hz using AC bridges.
