Background Research Form background reading and research I have discovered that for most materials that conduct electricity there is some degree of variation of resistance with temperature. There is a set equation governing this change as follows; R? = R0(1+??) = R0 + ?R0? Where R? = Resistance at Temperature ? R0 = Resistance at 0?C ? = The temperature coefficient of resistance. As we will see after we have done the experiment the temperature coefficient will turn out to be negative as I am sing a N.T.C. Thermistor Apparatus * Negative temperature coefficient thermistor. * Voltage meter (V) * Ammeter (A) * Power Pack (Low voltage DC) * Freezer * Heater * Beaker * Thermometer Diagram The Variables In this section I will look at all the possible...
