Introduction.

According to ohms law, a higher resistance simply means a larger amount of energy is used to move the electrons through the wire as they collide with the atoms. Therefore resistance is measurement of how much energy is used to push the current through a substance or material.
In this experiment I will be judging the connection between a wires length and its resistance. In theory, if I were to half the length of a wire the amount of moving electrons would be halved and therefore the amount of collisions between the atoms and electrons would be halved as well.

Practical Procedure.

Apparatus.
*NOTE* I have selected the chosen apparatus from a range of equipment, the chosen apparatus happened to be the most efficient.
I will need one meter of Nichrome wire, a power pack to use as a source power, a voltmeter to measure the exact amount of volts being passed through the Nichrome, two crocodile clips attached to wire, so......
