Question 421: Current Electricity

Question

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

Accepted Answer

At cold junction, current flows from Antimony to Bismuth (because current flows from metal occurring later in the series to metal occurring earlier in the thermoelectric series).

Answer

flow from Antimony to Bismuth at the hot junction

Answer

flow from Bismuth to Antimony at the cold junction

Answer

now flow through the thermocouple

Answer

flow from Antimony to Bismuth at the cold junction
