Thomson coefficient

Vedclass · Answer

(B) The heat $H$ evolved or absorbed in a conductor due to the Thomson effect is given by the formula: $H = \sigma i t \Delta 	heta$,where $\sigma$ is the Thomson coefficient,$i$ is the current,$t$ is the time,and $\Delta 	heta$ is the temperature difference between the ends of the conductor.Given the conditions: $i = 1\, A$,$\Delta 	heta = 1\, ^oC$,and $t = 1\, s$.Substituting these values into the equation:$H = \sigma 	imes 1 	imes 1 	imes 1 = \sigma$.Thus,the amount of heat evolved or absorbed per unit current per unit time for a unit temperature difference is defined as the Thomson coefficient.

The Thomson coefficient of a conductor is $10 \mu V/K$. The two ends of the conductor are kept at $50^{\circ} C$ and $60^{\circ} C$, respectively. The amount of heat absorbed by the conductor when a charge of $10 C$ flows through it is:

Temperature of cold junction in a thermocouple is $10^{\circ} C$ and neutral temperature is $270^{\circ} C$, then the temperature of inversion is (in $^{\circ} C$)

$A$ battery is charged at a potential of $15\, V$ for $8$ hours when the current flowing is $10\, A$. The battery on discharge supplies a current of $5\, A$ for $15$ hours. The mean terminal voltage during discharge is $14\, V$. The "Watt-hour" efficiency of the battery is .............. $\%$
