How does electrical voltage appear at the ends of a thermocouple?
| October 23, 2020 | Education
When one end of a long metal conductor is heated, some of the electrons diffuse from the higher temperature end to the colder end. The cold end is charged negatively. Conductors made of different metals have different concentrations of free electrons. Therefore, with the same temperature difference between the cold and hot ends, different electric voltages arise for conductors made of different metals.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
