How does the resistance of nichrome wire depend on its length?

Procedure:

In order to investigate how the resistance of nichrome wire depends on its length I will firstly have to know the formula for resistance (resistance = voltage ÷ current). So, in order to find the resistance of a length of nichrome

Conclusion

Conclusion:

For the conclusion I would like to state that for every 5cm decrease in the length of nichrome wire, the voltage decreases by approximately 0.1 V, whilst the resistance decreases by approximately  0.7 (from 45-40cm), followed by 0.6 (from 40-35cm), followed by 0.5 (from 35-30cm).

  1. Investigating how the resistance of Nichrome wire depends on its length

    I can conclude that if length increases, resistance shall also increase. And we can now take figures from the graph to prove this; 20cm length gives us 0.965? but 60cm length gives us 2.601?. We also have another trend. If we double length from 20cm to 40cm we get 1.791?.

  2. An experiment to find the resistivity of nichrome

    I would also investigate other factors, such as temperature, voltage and current, and see how these effect the resistance. I would also do the experiments under different conditions such as temperature and pressure to see if it makes any difference to resistance.
