====Improving [[Precision]]====
: Use an Ensure the same wire is used for all repeat readings to reduce the [[ammeterRandom Error|random error]] with a greater .: Ensure the wire is straight along the ruler to reduce the [[resolutionRandom Error]]caused by inconsistencies in the length of the ruler.: Use a [[voltmeter]] with a greater [[resolution]]pointed contacts to connect to the wire to reduce the uncertainty of the length due to thick/wide contacts during repeat readings.
