Determination of r for a Metallic Conductor
Aim:
To determine the resistivity (r) of a given sample of wire
Introduction:
Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be …showed first 75 words of 1151 total…

- In addition, the wire was not connected properly to the circuit since the crocodile clips touched only some parts of the wire. There should be better contacts to the wire; the wire should be surrounded completely. Soldering the contacts to the wire will minimize this uncertainty.
