Q. When a current of 1 ampere is passed through a conductor whose ends are maintained at temperature difference of $1℃,$ the amount of heat evolved or absorbed is called
A) Peltier coefficient
B) Thomson coefficient
C) Thermoelectric power
D) Thermo $e$.m.f.
Explanation
(b) $H = \sigma it\Delta\theta \Rightarrow$ If$\ i = 1A,\ \Delta\theta = 1℃,t = 1sec$ then$\ H = \sigma$
