All household circuits are wired in parallel. A 1220-W toaster, a 310-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?
I_(toaster) = ◻A
I_(blender) = ◻A
I_(lamp) = ◻A
(b) To see if this combination will blow the 15-A fuse, find the total current used when all three appliances are on.
I_(total) = ◻A
