Grundlagen Elektrotechnik: Die elektrische Spannung

Elektrotechnik Die elektrische Spannung

Die am häufigsten genutzte Größe zur Klassifizierung der verschiedenen Arten der Elektrizität ist die Spannungseinheit Volt. Was aber bedeutet Spannung? Wie wird sie erzeugt, was bewirkt sie, und wie kann sie sicher gemessen werden?

Wenn ein angehender Kfz-Mechatroniker das erste Mal mit der Elektrik zu tun hat, dann handelt es sich häufig um Arbeiten an der Autobatterie, zum Beispiel die Ruhespannung der Batterie messen, den Akku ausbauen oder laden. Und er weiß auch sicherlich sofort, dass der Akku 12 V Spannung hat. Doch wenn es nun darum geht, die Spannung zu erklären, so wird er vermutlich ein wenig ins Stocken geraten.
