Improving Precision
====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 pointed contacts to connect to the wire to reduce the uncertainty of the length due to thick/wide contacts during repeat readings.: Ensure a low [[Electrical Current|current]] throughout to reduce the [[heating]] effect of the [[Electrical Current|current]] on the [[wire]]. This improves [[voltmeterprecision]] with a greater when done over repeat readings because [[Electrical Resistance|resistance]] is affected by the [[temperature]] of the [[wire]] reducing the range of possible results for the same length or [[resolutionwire]].
