A copper-constantan (type T) thermocouple is used to measure the temperature of a liquid. The output temperature is 7.5 degrees celcius with the refrence junction maintained at 1.25 degrees celcius. What is the refrence and output emf of the fluid?

Step 1
The reference emf is the emf generated at the reference junction, which is maintained at a constant temperature. In this case, the reference junction is maintained at 1.25 degrees Celsius. The output emf is the emf generated at the measuring junction, which is Show more…

A copper constantan thermocouple produces an emf of 40 microvolt per degree celsius in the linear range of temperature. A galvanometer of resistance 10 ohm and capable of detecting a current of one microampere is employed. What is the smallest temperature that can be detected by this arrangement? (a) $0.25^{\circ} \mathrm{C}$ (b) $1.00^{\circ} \mathrm{C}$ (c) $0.50^{\circ} \mathrm{C}$ (d) $2.00^{\circ} \mathrm{C}$
A copper-constantan thermocouple can generate a voltage of $4.75 \times 10^{-3}$ volts when the temperature of the hot junction is $110.0{ }^{\circ} \mathrm{C}$ and the reference junction is kept at $0.0^{\circ}$ C. If the voltage is proportional to the difference in temperature between the junctions, what is the temperature of the hot junction when the voltage is $1.90 \times 10^{-3}$ volts?
