Resistor's Linearity Testing
Isao Minowa, Hiroyuki Tominaga · 2004
We need not only precisely made resistor but also ohmic (linear) one. Three type of resistors such as carbon, metal film and foil, which values are selected close to quantum Hall resistances of 6.4532kOmega and 12.906kOmega, were tested at room temperature by the dual frequency method and the third harmonics measuring method, because QHR would be thought as perfect linear resistances within there current limits
