"WebHigh values of resistivity imply that the material making up the wire is very resistant to the flow of electricity. Low values of resistivity imply that the material making up the wire transmits electrical current very easily. The unit of resistivity is the ohm meter (Ω m). The resistivity ρ (rho) of a material is given by " - Resistivity of a wire experiment results

WebForget the highway analogy. The resistance of a wire depends on 3 parameters: the conductivity of the material from which the wire is made, its cross sectional area, and its length. Highly conductive materials, such as copper and silver, are used to manufacture wire to achieve a low resistance. WebPredicts that the longer the wire the more resistance it will have as there are more atoms for the electrons to hit. Explains that thin wire is created by rolling out a thicker peace there is less space between atoms for the electrons to flow through. Describes the method of measuring voltage and current for 100 centimetres of 30 swg resistance ...
