Spannung und Strom

Elektronen, die durch einen Leiter fließen können Arbeit verrichten (LEDs können leuchten, Motoren können sich drehen). Man spricht von elektrischer Energie. Damit sich Elektronen bewegen ist ein Potentialunterschied nötig. Auf der einen Seite muss ein Elektronenüberschuss (GND oder Minus-Pos), auf der anderen Seite ein Elektronenmangel (5V+ oder Plus-Pol) vorliegen.
Der Elektrische Strom (I) bezeichnet die Anzahl [...]
