A thermocouple is made from two metals, Antimony and Bismuth. If one junction of the couple is kept hot and the other is kept cold, then, an electric current will

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 ?

A thermocouple of resistance 1.6 Omega is connected in series with a galvanometer of 8 Omega resistance. The thermocouple develops and e.m.f. of 10 mu V per degree temperature difference between two junctions. When one junction is kept at 0^(@)C and the other in a molten metal, the galvanometer reads 8 millivolt . The temperature of molten metal, when e.m.f. varies linearly with temperature difference, will be

A thermo couple is formed by two metals X and Y metal X comes earlier to Y in Seebeck series. If temperature of hot junction increases beyond the temperature of inversion. Then direction of current in thermocouple will so

State the condition at which we say to the two coils kept close to each other areperfectly coupled with each other.

The e.m.f of a thermocouple one junction of which is kept at 0^@C , is given by e=at+bt^2 The neutral temperatue will be

If the cold junction of thermocouple is kept at 0^(@)C and the hot junction is kept at T^(@)C , then the relation between neutral temperature (T_(n)) and temperature of inversion (T_(i)) is

If the cold junction of thermocouple is kept at 0^(@)C and the hot junction is kept at T^(@)C , then the relation between neutral temperature (T_(n)) and temperature of inversion (T_(i)) is
