(The three devices are in parallel when plugged into the same outlet.) Assume that this is the standard household 120-V circuit with a 15-A fuse. (a) What current is drawn by each device? oaster blender- amp (b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on. = total Additional Materials eBook

Explanation / Answer

power= voltagex current

(a)Itoaster=1240/120=10.33A

Iblender=230/120=1.92A

Ilamo=70/120=0.583A

(b)Itotal=10.33+1.92+0.583=12.83A
