Thermocouple-Uses and how it Works??? 1. The problem statement, all variables and given/known data I need to investigate how current in a diode varies with extreme temperatures. I have no idea how to do this but could a thermocouple somehow be incorporated into the investigation. 2. Relevant equations Can a thermocouple be used to investigate this 3. The attempt at a solution I have no idea how a thermocouple works or what it exactly does, so i have no attempted solutions.
