The effects of the distance between two plates in copper solution on the current. Introduction I am investigating the relationship between the distance between two metal plates in a copper sulphate solution and the effect it has on the electrical current across the two plates. Scientific Knowledge Resistance is the amount a substance resists the flow of charge flowing through it. How Resistant a substance is depends on 4 things: 1. The length of the wire- the longer the wire the bigger the resistance; if you double the length you double the resistance. 2. The thickness/ surface area- doubling the area will halve the resistance. 3. The material- the more free electrons there are to carry charge around the circuit the lower the resistance of the wire. 4. The temperature- the warmer the wire the more vigoursly the atoms vibrate impeding the flow of charge thereby increasing the resistance. For example if you had a corridor with students...
