Unformatted text preview: with a thermometer. Begin heating water and taking readings of the temperature and resistance ever 5 degrees. Make a graph with this data of resistance vs 1/T. Conclusion From comparing our data table to our graph we see that is only applies over a certain range and we see this range is between temperatures 30 degrees and 70 degrees Celsius. After that it seems the resistance levels off. The slope of our graph represents the exponential temperature coefficient value. A lot of applications would need to know at what temperature you will get this resistance. When you power a circuit it creates heat and heat changes the resistance which in turn changes the circuit. This is a very useful device....
