An Investigation into the Resistance of a Thermistor, its Application as a Sensor and Within a Potential Divider In a Brewery, the conditions need to be controlled to maintain an efficient rate of reaction. If the temperature rises above 40?C, enzymes involved in the reaction become denatured. Therefore, within the reactor, there needs to be some sort of temperature sensor which signals a warning when the temperature is greater than this. Resistance simply means the "opposition to the flow of electric current." Resistance is important because it has a controlling effect on the amount of current which flows with an applied voltage. Materials that have few free electrons and so do not allow current to flow through them have a very high resistance are called "Insulators". Materials which have free electrons are lower in resistance and are called "Conductors"...current flows freely through them...and there are of course materials in between the two...
