Restistance of Nichrome wire
Investigating the resistance of Nichrome wire.
Aim In this investigation, I am going to be invstigating how the length of Nichrome wire affects the resistance that is applied.
Prediction In 1826, Georg Ohm discovered that the current flowing through a metal wire is proportional to the potentail difference across it, it basically means if you double the potential difference you double the current. The thin wire in a lamp tends to resist the movement of electrons …

…the same through out the whole experiment, I will also have to keep the voltage the same otherwise it might affect the results, however the most important factor I will have to look out for is the temperature 'As temperature increases, resistance of wire increases' if the temperature changes the resistance will change with the temperature, this factor may affect my results significantly, and there may be nothing to stop this factor affecting my results.
