# Physics Assesment : Copper wires resistance

Hi. This may seem extremely easy for all you guys here but seeing as Im 15 its not quite as simple to me.
Firstly the assesment im going to be doing will count for my GCSE therefore i want the best possible result (Btw im taking triple science)
Can someone with as much detail as possible explain a good "prediction" since im not 100% sure if the thing im writing is correct therefore i need some help :S thanks

$$R = \rho \frac{L}{A}$$
