Question:

In a certain experiment, cylindrical samples of diameter 4 cm and length 7 cm are used (see Fig. 16€“9). The two thermocouples in each sample are placed 3 cm apart. After initial transients, the electric heater is observed to draw 0.6 A at 110 V, and both differential thermometers read a temperature difference of 8°C. Determine the thermal conductivity of the sample.
