Abstract
New shielded and unshielded resistance boxes and fixed standards of resistance for use in precise a-c measurements, are described in detail and numerical values are given for the residual inductance or capacitance of the individual coils and of the boxes at various settings, and for the resistance error at 1 and 50 kc. A new coil construction and two new types of decades are used. In one of the resistance boxes, for any setting of the dials, only one coil of each decade is in the circuit, while the idle coils are completely disconnected, and in addition the configuration of the circuit inside the box remains constant for all settings of the dials.
