Aim: The aim of this investigation is to find out the relationship between resistance and conductive putty, and to see how length of putty affects this relationship. The Experiment: Conductive putty is specially designed to be a conductor; this is achieved by adding carbon black. This can easily be used to prove the concept of resistivity because it is malleable and so the cross-sectional area, length and shape can easily be changed. This experiment will show the effects on resistance in a circuit, as the length of putty decreases. I will be using 30cm of putty, and decreasing it by 5cm each time. First the voltage of the battery will be taken using a voltmeter, and this will be recorded at the start of the experiment. Then a circuit will be constructed containing the battery, the ammeter and putty. See diagram. For each different length of putty, a reading will be recorded from the ammeter...
