Calculable Coaxial Resistors for Precision Measurements
IEEE Instrumentation and Measurement Technology Conference , May 24-26, 1999 , Venice, Italy - May 01, 1999

Coaxial straight-wire resistors have been constructed with the purpose of improving comparisons between resistors, capacitors, and inductors in the audio frequency range. The design is based on the principle that a coaxial line with a cylindrical shield can be described by relatively simple equations for the real and imaginary parts of the impedance. The resistors, with values at and above 100 ohms, will be used as transfer standards for characterization of the frequency dependence of standard resistors and of the quantum Hall resistance in the audio frequency range.
