Problem 30213.

The galvanometer circuit includes a thermocouple consisting of copper and constantan wire, 1 m long and 0.2 mm in diameter. By how many divisions will the galvanometer needle deviate if the thermocouple junction is heated by 50°C? The internal resistance of the galvanometer is 50 Ohm, the sensitivity of the galvanometer is 10^-6 A/div, the sensitivity of the thermocouple is 40 μV/K.
