Objective: Verification of Ohm’s law
In simple electrical conductors, the current I which passes through the conductor is proportional to the applied voltage U. The constant of proportionality, the ohmic resistance R, is dependent on the length x of the conductor, its cross-sectional area A and the nature of the material. This relationship is to be investigated using constantan and brass wires.
