Current Electricity Charging Discharging Of Capacitors Question 110

Question: A thermo couple develops $ 200,\mu ,V $ between $ 0^{o}C $ and $ 100^{o}C. $ If it develops $ 64\mu ,V $ and $ 76,\mu ,V $ respectively between $ (0^{o}C-32^{o}C) $ and $ (32^{o}C-70^{o}C) $ then what will be the thermo emf it develops between $ 70^{o}C $ and $ 100^{o}C $

Options:

A) $ 65\mu ,V $

B) $ 60\mu V $

C) $ 55\mu V $

D) $ 50\mu V $

Show Answer

Answer:

Correct Answer: B

Solution:

By using $ e _{0}^{100}=e _{0}^{32}+e _{32}^{70}+e _{70}^{100} $

Therefore $ 200=64+76+e _{70}^{100} $

Therefore $ e _{70}^{100}=60,\mu V $
