Question

A thermo couple develops 200 μV between 0^oC and 100^oC. If it develops 64 μV and 76 μV respectively between (0^oC – 32^oC) and (32^oC – 70^oC) then what will be the thermo emf it develops between 70^oC and 100^oC

• A. 65 μV
• B. 60 μV
• C. 55 μV
• D. 50 μV

Answer 1

Answer: (B)

60 μV

Answer 2

By using $e_{0}^{100} = e_{0}^{32} + e_{32}^{70} + e_{70}^{100}$⇒ $200 = 64 + 76 + e_{70}^{100}$ ⇒ $e_{70}^{100} = 60\mu V$
