1. The problem statement, all variables and given/known data "You are required to design a laboratory experiment to investigate how the current in a diode varies with temperature in the range of -20 to +150 Degree's C" 2. Relevant equations N/A 3. The attempt at a solution Perhaps using a freezer for the negative temp's and a oven/kiln for high end temp's. Use a themocouple to measure the temp' (Using ICE - 0^C). I wondered: How to attach the termocouple to the diode, (if thermopaste - which one?) Which diode? (Can withstand -20 up to +150) What Volatage Power Supply? 3V? How to ensure it was all accurate and reliable? I have a rough idea of the circuit diagram. Any help would be appreciated. Thanks!
