摘要：
We developed a cryogenic current comparator, to which current of up to 1 A can be supplied. It was designed to be used for a resistance ratio bridge to measure current dependence of a 1 Omega resistor from 50 mA to 1 A by comparing it to a 100 Omega resistor with small power coefficiency. It was also designed to be inserted in a superconducting coil to measure superconducting current.
