In physics, the resistance of a strand of wire is affected by four factors: the material of the wire, its thickness, its temperature, and its length. In my experiment, our group chose to study the effect of the thickness of wire on resistance.

There are four factors which can affect the resistance of a wire, these are:

1. Material of Wire
2. Thickness of Wire
3. Temperature of Wire
4. Length of Wire

Material of Wire

Some metals are better conductors than others, metals such as Gold and silver are very good conductors but also are very rare and expensive. These metals have very little resistance.

Thickness of Wire

The thicker the wire the more space there will be for the current to flow. This means that the electrons have a lesser chance of hitting the atoms and causing resistance.

Temperature of Wire

The warmer the conductor is the faster its atoms...
