The calibration data of a thermocouple with its cold junction at 0°C are given below. The hot junction of the thermocouple is placed in a bath at 80°C, while its cold junction is at 20°C. What is the emf of thermocouple ?
Correct answer: C
Explanation
The emf is calculated using the ratio of voltages at 80°C and 20°C. The value closest to the calculation based on the provided data points is 2.46 mV.
