The constant of a constantan-copper thermocouple is: `4.3xx10^(-2)mV//K`. The resistance of the thermocouple is 0.5 ohm, that of the galvanometer 100 ohm. One junction of the thermocouple is immersed in melting ice, the other in a hot liquid. What is its temperature if the current in the circuit is `56muA` ?

Answer

`131^(@)C`
