Description

The experiments P7.2.2.1 and P7.2.2.2 measure the resistance values as a function of temperature using a Wheatstone bridge. The computer-assisted CASSY measured-value recording system is ideal for recording and evaluating the measurements. For the noble metal resistor, the relationship

is verified with sufficient accuracy in the temperature range under study. For the semiconductor resistor, the evaluation reveals a dependency with the form

with the band spacing E = 0.5 eV.
