Answer
Thermistor
Explanation
This question belongs to the branch of Physics known as Electronics. It specifically deals with the characteristic of electrical components in relation to temperatures. The component that has high resistance at low temperatures and low resistance at high temperatures is called a Thermistor. Most common thermistors are Negative Temperature Coefficient (NTC) types i.e. their resistance decreases as the temperature increases. The opposite, Positive Temperature Coefficient (PTC) thermistors, have a resistance that increases as the temperature increases.
