Temperature dependence of different resistors and diodes with the FG module and Cobra3

Product No: P2410415

Principle

The temperature dependence of an electrical parameter (e.g. resistance, conducting-state voltage, blocking voltage) of different components is determined. To do this, the immersion probe set is immersed in a water bath and the resistance is measured at regular temperature intervals.

Tasks

Measurement of the temperature dependence of the resistance of different electrical components.
Measurement of the temperature dependence of the conducting state voltage of semiconducting diodes.
Measurement of the temperature dependence of the voltage in the Zener and the avalanche effects.
