The current that you can put through a wire depends on the voltage you apply and the resistance of the wire. In fact;
current = voltage/resistance
Current is the sum effect of electrons moving through the wire. When the wire heats up, for example, by a torch, it causes increasing chaos in the wire, or entropy. This chaos causes the electrons to bump around more than before. Therefore, flow is with less ease. This means that the copper wire now has a higher resistance. Most metals increase their electrical resistivity by about 0.005 per degrees. So, if the resistivity of copper at 25 C is 1, then at 500 C it will be;
1+500x.005=3.5
This means if you heat your wire to 500 C, then its resistance increases 3.5 time! The current through it then drops by 3.5 times.

What is the relationship between temperature and air conductivity?
The relationship between temperature and air conductivity is that as temperature increases, air conductivity also increases. This means that higher temperatures can lead to better conductivity of electricity through the air.
What is the relationship between temperature and conductivity?
The relationship between temperature and conductivity is that conductivity generally increases as temperature increases. This is because higher temperatures cause particles in a substance to move more quickly, which allows for better flow of electric current.
When the temperature increases conductivity of conductor?
When the temperature of a conductor increases, the conductivity typically decreases. This is because higher temperatures cause the atoms in the conductor to vibrate more, leading to more collisions between electrons and atoms. As a result, the flow of electrons is impeded, reducing the conductivity of the material.
How does thermal conductivity change with temperature?
Thermal conductivity generally increases with temperature. This means that as temperature rises, materials are better able to conduct heat.
What is the relationship between specific heat and thermal conductivity in materials?
The relationship between specific heat and thermal conductivity in materials is that specific heat measures the amount of heat needed to raise the temperature of a material, while thermal conductivity measures how well a material can transfer heat. Materials with high specific heat can absorb more heat without a large temperature change, while materials with high thermal conductivity can transfer heat quickly.

How do thermometers with in liquid in glass measure temperature?
Such thermometers are based on the fact that the liquid expands when the temperature increases. That's what the thermometers measure.
