Temperature dependence of different resistors and diodes



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.

Benefits

• One setup to measure both electrical components and semiconducting diodes, as well as the blocking voltage
• All immersion probes are mounted on one convenient heat-resistant circuit board for easy handling

Tasks

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