Students have asked these similar questions
d. the temperature between interfaces of two layers of insulation.
In temperature measurement experiment, if three temperatures are considered (50 °C, -5
°C, and 20 °C) the measured voltage according to Peltier law, respectively will be (knowing
that the ambient temperature is equal to 20 °C):
Select one:
a. Positive, zero, and positive.
