SUMMARY
This discussion focuses on measuring heat capacity at low temperatures, specifically around 10K. Key techniques include using resistive heating elements and low-temperature thermocouples, which can be sourced from suppliers like Kurt J Lesker. Calibration of the cold finger's heat capacity is essential for accurate measurements. The energy imparted by the resistive heater is calculated using the formula energy = power * time = R * I^2 * time.
