Abstract
EXPERIMENTS recently carried out in this laboratory have shown that it is practicable to heat the wires of a thermocouple by the passage of an electric current and at the same time to record the temperature of the junction by means of the thermo-E.M.F. A high-frequency current is used in order that the concomitant voltage (order 10 volts) may be separated from the thermo-E.M.F. (order 0.001 volts) by means of inductance-capacitance filters. The apparatus can be used for measuring the thermal constants of poor conductors placed in contact with the couple wires.
