Principle

The current-voltage characteristic of a semiconducting diode is measured.
The collector current in dependency on the emitter-collector voltage is measured for different values of base current strength through a NPN transistor.

Benefits


Fast and easy experimenting

Get to know the behaviour of several types of semiconductors

Simplified implementation: all pre-settings already prepared

Data logging reveals instantaneous results during measurement


Tasks


To investigate the dependence of the current strength flowing through a semi-conducting diode.

To determine the variations of the collector current with the collector voltage for varios values of the base current intensity.
