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
- Option 1)
flow from antimony to bismuth at the cold junction
- Option 2)
flow from antimony to bismuth at the hot junction
- Option 3)
flow from bismuth to antimony at the cold junction
- Option 4)
not flow through the thermocouple.
Answers (1)
In thermocouple , current flows across the cold function from the later occuring metal in the series to the one occuring earler .in thermo electric series , Bismuth comes earler than antimony . So at cold function current flows from Antimony to Bismuth and at hot function from bismuth to antimony
Option 1)
flow from antimony to bismuth at the cold junction
Option 2)
flow from antimony to bismuth at the hot junction
Option 3)
flow from bismuth to antimony at the cold junction
Option 4)
not flow through the thermocouple.
