It is described, in this paper, the design and construction of coaxial calculable resistors, with values of 140 W, and 1000 W, to be used as resistance standards in alternative current. Their behaviors are evaluated using simulation techniques and the step response. Impedance variations lower than 10-11 at 1600 Hz were obtained.
