All household circuits are wired in parallel. A 1230-W toaster, a 210-W blender, and a 55-W lamp are plugged into the same outlet. (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? A A A Itoaster = Iblender = Ilamp= (b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on. Itotal = A
