Whether mixer or tram, hair dryer or model train transformer. We encounter electrical engineering everywhere and alternating current plays a special role. Direct and alternating current are researched in exciting experiments. The AC generator generates a completely harmless AC voltage. This enables phenomena such as resonance, high, low and bandpass behavior to be generated and explained with increasing and decreasing current strengths with frequency changes. To try out the new knowledge, the young researchers build various alarm systems and measuring devices from the compact electronic components.
