As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.
Reduce the temperature of the conductor.
Any substance that has an electrical resistance will convert electrical energy to heat - in other words, most substances. The exception are superconductors. A device specifically designed to dissipate electrical energy is called a resistor or resistance.

The property of a substance enabling it to slow down electricity is called resistance and is measured in ohms. This ability is called electrical resistance. Every substance has this. Gold has the minimum resistance for electricity. Such substance is called electrical conductor. And there are substance where the electrical resistance is affected by heat, light and other conditions. And for those substance where electricity can not flow are called electrical insulators (non-conductors) such as wood and ceramics.

Reduce the temperature of the conductor.
pure water does not conduct electricity. the presence of electrolytes in the water is what conducts electricity. the equation for the conductivity (ability to conduct electricity) Conductance = 1/ resistance
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

it decreases.
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
