# Physics Coursework Gcse Resistance Wire

I will do this by going through all of the factors that affect the resistance of a wire and how I would measure each factor to find out which would be the most effective and easiest factor to measure.

The number of electrons depends on the amount of electrons in the outer energy shell of the atoms, if there are more or larger atoms then there must be more electrons available.

If the material has a high number of atoms there will be a high number of electrons causing a lower resistance because of the increase in the number of electrons.

The word 'ideal' is another way of saying the conductor follows Ohms law without needing to invoke thermal considerations or any other parameter which would cause a deviation form Ohms law such as inductance, capacitance etc.

Before starting my coursework I have decided to choose 2 factors that will affect the resistance of a wire.

The resistance of a wire depends on the number of collisions the electrons have with the atoms of the material , so if there is a larger number of atoms there will be a larger number of collisions which will increase the resistance of the wire.
