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.
