... electrons making the resistance of the putty larger. When the length of the putty is small then there are less free moving electron which pass the electricity and therefore not as many for the electricity to jump through in order to conduct. Whilst passing on the electricity some energy is lost and when the putty is longer it will loose more energy than if it was shorter as there are more electrons to move through. This therefore means that the resistance of a longer piece of putty is greater than a shorter piece. I also predict that if the current is changed it should not effect the resistance of the putty. This is because as the current changes so should the voltage. The equation for resistance is voltage/current. (R=V/I). This means that because the current increases so will the voltage but once the resistance has been worked out it should be ...
