Description

The experiments P7.2.1.1 and P7.2.1.2 determine the Hall coefficient RH of two electrical conductors by measuring the Hall voltage UH for various currents I as a function of the magnetic field B. A negative value is obtained for the Hall coefficient of silver, which indicates that the charge is being transported by electrons. A positive value is found as the Hall coefficient of tungsten. Consequently, the holes are mainly responsible for conduction in this metal.
