Hey. I have to design a laboratory experiment to investigate how the resistance of a house brick varies with temperature in the range of 20 degrees C and 800 degrees C. I know that resistance of a brick is very high so I'll need to use a high voltage, perhaps 5000V. The main problem i have is figuring out: 1. How the brick is to be heated. 2. How to measure the temperature of the brick. 3. And how to heat the brick up without heating any of the connecting cables as that would just make the resistance appear to be higher once the values for the voltage and current are recorded. I thought about using a blow torch near the brick and heating it up, but then couldn't figure out how to measure the temperature, and how to maintain the temperature of the brick, and how to keep a fairly even temperature all the way round the brick. Any suggestions? Thanks.
