WebResistivity is the ability of a material (such as water) to resist the flow of electricity. Resistivity is the reciprocal of conductivity, such that. Resistivity = 1/Conductivity. From this relationship, we can see that water with a high conductivity has a … WebResistivity is a material property of the conductor. It depends only on the temperature of the conductor and not on the length or density of the material. Increasing the length increases the resistance of the body but not the resisitivity.
