Determination of the resistivity of nichrome wire The experiment The aim of the experiment was to investigate the resistivity of a piece of nichrome wire. The equipment was set up as below. The current and voltage were measured and then the results manipulated to produce resistance values. The results table and methods for the calculations are attached. Cellotape is used to secure the wire to the ruler and so ease measurement of the length of wire. The jockey is used to make good contact with the wire and so improves reliability. The jockey is better than a crocodile clip because it has better contact and so eliminates any problems with loose connections between the crocodile clip and wire. The current is kept below 0.5 A to avoid over heating and melting of the wire. About Resistivity The resistivity of a piece of wire depends upon three things, the resistance, the length...
