In a metal with positive Thomson coefficient, current is passed from the lower temperature to higher temperature side. Then heat will be
Options
- Aabsorbed
- Bconstant
- Cevolved
- Deither ' ' or ' '
Correct answer
A. absorbed
Step-by-step solution
According to Thomson's effect the potential at a point of lower temperature is lower than at the point at higher temperature which is at higher potential. When current is passed from lower temperature to higher temperature of a metal, work is to be done, hence energy is absorbed.
