Using liquid nitrogen as the refrigerant, students will measure electrical resistance over a. temperature range from -196 Â°C (77 K) to room temperature, approximately 22 Â°C (295 K). Introduction to Research: In 1911, while investigating the conductivity of various metals at temperatures near the boiling. point of liquid helium (-269 Â°C, 4 K), H. Kamerlingh Onnes found that the electrical resistance. of mercury dropped to a value so small that it was indistinguishable from zero.
