Lineare Kennlinie NTC Widerstand

Beitragvon Benni » 07.02.2013, 15:56

Hallo :) , brauche für die Schule eine Lineare Kennlinie von einen NTC Widerstand bis morgen :!: ich hab schon in Internet nachgeschaut aber ich finde nur nicht Lineare Kennlinien von NTC Widerstand :x kann mir jemand bitte helfen :)
Etwas selber zu bauen, macht mehr Spaß als zu kaufen :) ;)

Danke, die Aufgabe heißt übrigens: Zeichne die lineare Kennlinie eines temperaturabhängigen Widerstandes mit Warmleiter Eigenschaften?
Edit: Da muss man schon eine Lineare Kennlinie von eine NTC Widerstand zeichnen, oder?

Dann kannst du nur die U zu I Kennlinie bei konstanter Temperatur zeichnen.
Oder Gewicht zu Temperatur.


Psst:
Was der Lehrer vermutlich sehen will ist, dass der Widerstand mit Temperaturerhöhung nach unten geht. Dass dieser Strich nicht linear ist weiß er vermutlich garnicht. Mach einen Strich von links oben nach rechts unten und denk dir dein Teil. :mrgreen:

Oder er meint: mit linearer Skalierung :roll:

Manchmal muss man einfach fragen, was gemeint ist. Immer diese Sache mit der Kommunikation.
Vielleicht eine Scherzaufgabe. Et is Karneval! :D

Hol mal die Gewichte für die Wasserwaage....
