Abstract

This paper describes the thermal characterization of a coaxial calculable resistor, part of traceability chain of the capacitance unit to the quantum Hall effect, in construction at Inmetro. The realization of the capacitance unit (farad) is related to the QHE by a calculable coaxial resistor, and three low-uncertainty coaxial bridges: the two-terminal and the four-terminal bridges, already in operation at Inmetro; and the quadrature bridge, in final stage of construction.
