    If the wire obeys Ohm's Law, no matter the voltage and current, the value obtained for resistance from the formula R=V/I, should be the same, meaning three values for one resistance can be obtained, which, if they show to be equal to within experimental error, improves the reliability of the value of R obtained.

  1. Finding the Resistivity of a Wire

    If I work out the resistivity based on this result only, I get a value of 1.59x10-6 ?m, which gives the spread of my results to be just 4.70x10-7 ?m, which I believe is very accurate. There was very little discrepancy in my data.

  2. Physics - Resistivity

    At high temperatures, the resistance of a metal increases proportionately with temperature. This can be shown in this diagram As the temperature of a metal is reduced, the temperature dependence of resistivity follows a complex temperature rule. Mathematically the temperature dependence of the resistivity '?'

  1. Measuring The Resistivity Of A Pencil Lead.

    If the resistance did fluctuate I would need to change the current, as the rise in temperature of the pencil would affect resistance and thus my results. My results from these settings are as follows : Pencil Length Voltage Current Resistance 171mm 1.03V 0.1A 7.923?
