Thermistors are resistors whose value changes with temperature. Operation Thermistors are negative-coefficient devices—their resistance decreases as the temperature increases
What is Resistivity? Resistivity is just a property of the conductor.Every material has a resistivity.It is actually the resistance of a 1m long piece of wire with across-sectional area of 1m2.As you can imagine this is always a very low number.For Copper ρ = 1.72 x 10-8 Ωm Units = Ωm
