Physics - Heat & Thermo Question with Solution | TestHub

Thermocouples measure temperature in the linear emf-temperature region. Thermoelectric powers of Pt and Ni are -4 and $-20\mu {\mathrm{V}}^{\circ }{\mathrm{C}}^{-1}$. With cold junction at $0^{\circ }C$ and hot at $100^{\circ }C$, emf magnitude is:
