Calculer le temps de consommation 

E=Pxt  (P=watt)(t=s)(E=W.s ou J)

Remarque on a aussi kwh donc t=heure 

Rendement Netat=Psortie/Pentree 

Exemple 

Équation de la droite :à=yb-ya/xb-xa

à=3,60-3,45/0,117-0,138=-7,1



Recherche de b: b=y-axx

b=3,6-(-7,1x0,117) b=4,43V

équation de la droite y=-7,1x+4,43

5)comme Upn=E-rxI comme Upn=y et I=x

Par identification E=4,43v  r=7,1hom

Soit Upn=4,43-7,1xI
