The effect of temperature on conductivity and resistance
So, I think that when the temperature of my wire increases, the resistance of the wire will also increase making the conductivity of the wire reduce. I believe that the opposite would happen if there was a decrease in temperature.
Conductivity is the inverse of resistance. The higher the resistance of the wire, the lower the conductivity will be. I am almost certain that temperature of the wire increases due to a power loss. The more current in the wire or even a higher amount of resistance will cause the temperature of the wire to increase. So, this basically tells me that the size and material of the wire will affect the experiment.
So why would resistance increase?
My reason of resistivity can be explained through the flow of current through the material. (Flow of current = The movement of electrons from one atom to another
-5m of Copper Wire with selected diameter (this experiment uses 0.5mm)
-Two 300mm PVC pipes
-6V high-capacity alkaline battery or power supply
-5 jumper wires with clips
-A plastic knife
-Insulation tape (black tape)
1. Firstly, wind your copper wire around the PVC pipe.
2. Tape the ends of the...
