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 It will be necessary for …

…went to more than two decimal places may also have helped this problem. Without knowing it, there may have been a large difference between the real answer, and the answer the ammeter I used gave me. For instance: 0.095A, 0.10A - 0.100A, O.104A. 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.
