Current Electricity Charging Discharging Of Capacitors Question 768
Question: Thomson coefficient of a conductor is $ 10\mu V/K $ . The two ends of it are kept at $ 50^{o}C $ and $ 60^{o}C $ respectively. Amount of heat absorbed by the conductor when a charge of 10C flows through it is
[EAMCET 2001]
Options:
A) 1000 J
B) 100 J
C) 100 mJ
D) 1 mJ
Show Answer
Answer:
Correct Answer: D
Solution:
By using $ H=\sigma Q\theta $
Therefore $ H=(10\times {{10}^{-6}})\times 10\times (60-50)={{10}^{-3}}J=1,,mJ $
