How is the resistance of a wire determined?
I will investigate the resistance of a wire in relation to its length. I predict that the longer the wire, the larger the resistance. This is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow.
What happens if you double the length of a wire?
To ensure accuracy, I have taken three readings each of volts and current. These results show that as the length of the wire increases, the resistance increases, as well. Furthermore, if you double the length of the wire, the resistance is roughly doubled.
Why are some conductors more resistance than others?
The metal is full of "free" electrons that do not stick to any particular atom; rather, they fill the space between the atoms. When these electrons move, they create an electric current. Conductors have resistance, but some are worse than others. The free electrons keep bumping into atoms.
Why are the results of my Wire experiment inconsistent?
There are possible sources of error that might have led to inconsistent results, such as a kink in the wire. This would have prevented the area of the wire from remaining constant and would have affected my results. However, I made sure that the wire remained straight throughout the experiment.
