Question

When a current of 1 ampere is passed through a conductor whose ends are maintained at temperature difference of 1 degree C, the amount of heat evolved or absorbed is called

  1. Peltier coefficient    
  2. Thomson coefficient    
  3. Thermoelectic power    
  4. Thermo e.m.f.    

The correct answer is: Thomson coefficient


    H equals sigma i t capital delta theta Þ If i = 1 A, Dq = 1°C, t = 1sec then H = s.
