Prinzip In diesem Versuch wird ein Windrad in verschiedenen Abständen vom Gebläse aufgestellt. Der Wind, der dann das Windrad erreicht, hat unterschiedliche Geschwindigkeiten. Vorteile
Aufgaben Welchen Einfluss hat die Windgeschwindigkeit auf die Spannung, die von einem Windrad produziert wird? Miss die Spannung, die das Windrad in den unterschiedlichen Abständen vom Gebläse erzeugt. Wiederhole den Versuch für verschiedene Versorgungsspannungen für das Gebläse.
