Posted on 2014-01-07 14:22:00 in Physics by JOSEPH

The thermo-electric power of iron is 17.3µ V /⁰C and 12.5 µV /⁰C at 100⁰C and that for silver 2.9 µV/⁰C at the same two temperatures. Calculate

1. 
   Peltier co-efficient between iron and silver at 100⁰C.


2. 
   Thomson co-efficient of iron at 50⁰C.


3. 
   Thermo e.m.f. when the two junctions are at 0⁰C and 100⁰C.


4. 
   Neutral temperature of the couple formed by the 2 metals.


5. 
   Temperature of inversion when the cold junction is at 50⁰C.
