Lenght Of Metal Wire Affects Resistance

INVESTIGATING IF THE LENGTH OF A METAL WIRE AFFECTS ITS underground rendering THE RESULTS: REACHING A CONCLUSION As the good continuation of the metal tele represent increased the vindication increased. This is shown in the graphical record of resistance against length of a metal wire. The resistance is without endure proportional to the length because it is a straight line graph through the origin. The mathematical formula for direct proportion throw out verify this. R= resistancek= a constantL=length R ? L R=kL |Length (cm) |Resistance () |k (?/cm) | |20 |0.70 |0.035 | |30 |1.15 |0.038 | |40 |1.42 |0.036 | |50 |1.80 |0.036 | |60 |2.18 |0.036 | |70 |2.48 |0.

035 | |80 |2.84 |0.036 | |90 |3.22 |0.036 | Difference between kH - kL = ?k = 0.038 0! .035 = 0.003 Percentage difference = (?k/ kL) x 100 = (0.003/0.035) x 100 = 8.57% This calculation shows in that respect is only 8.57% difference in the maximum and lower limit value of k. The constant value is very standardised this verifies that the affinity between the in mutualist inconsistent (the length of the wire) and the dependent variable (the resistance of the wire) is directly proportional. COMPARING CONCLUSION TO foresight AND EXPLAINING IT My prognostication was that as the length of the metal wire increased, its resistance would besides increase. I also predicted that the resistance of the wire would be directly proportion to its length.
