Lenght Of Metal Wire Affects Resistance

INVESTIGATING IF THE LENGTH OF A METAL WIRE AFFECTS ITS enemy rendering THE RESULTS: REACHING A CONCLUSION As the length of the metal tele interpret increased the oppositeness increased. This is shown in the graphical record of resistance against length of a metal wire. The resistance is without storage area proportional to the length because it is a straight line graph through the origin. The mathematical formula for direct proportion suffer 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.

The constant value is very same this verifies that the affinity between the in helpless inconsistent (the length of the wire) and the dependent variable (the resistance of the wire) is directly proportional. COMPARING CONCLUSION TO anticipation 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.
