The change of resistance through various lengths of wire.
Investigation into the factors that affect the resistance of a wire
PLAN
INTRODUCTION
Resistance is something in a circuit which slows down the current. Usually, the voltage and the resistance are balanced, but if you increase the resistance, less current would flow and if you increased the voltage, more current would flow. Resistance is measured in 'Ohms'.
Factors which affect resistance are: (of a wire)
· Thickness
· Temperature
· Length
· Width
· Material

However, changing the variable resistor would have made no difference. A computer may have been able to get extremely precise readings, and this would have been better than the ammeter used.
