The following topics are covered with the equipment set A1.1.1.3:
- The electric circuit
- The ohmic resistance
- Current and voltage sources
- The capacitor
- The coil
- The transformer
- The relay
- Special resistors like NTC, PTC or LDR
- The diode
- The Z-diode
- LEDs
- The transistor, and
- The thyristor.
Finally, with this set applied circuits in vehicle electronics can be assembled, such as:
- The electronic tachometer
- The electronic voltage regulator for three-phase generators, or
- The transistor control unit for breaker-triggered ignition systems.
The equipment in the STE suitcase lends itself for storage and as a student's workstation. It serves as a receptacle for various STE equipment sets in its cover and can be used to conduct experiments in the classroom. The cover can be separated from the base.
