Diode junctions on transistors, test circuit with light-emitting diodes

LP4.1.4.1

To carry out all experiments from this subject area, we offer you a complete set: CLICK HERE

Description

In this experiment, the students study the behaviour of an NPN and a PNP transistor with different polarities at the base and emitter, or base and collector. The students realise that the respective paths behave like diodes and create an equivalent circuit for the two transistors.
