Objective: Determine the electrical conductivity of copper and aluminium
Electrical conductivity of a material is highly dependent on the nature of the material. It is defined as the constant of proportionality between the current density and the electric field in the material under investigation. In this experiment, four-terminal sensing is used to measure current and voltage in metal bars of known cross section and length.
