Assume that a coffee maker, a vacuum cleaner, a toaster, and an electric drill were all used for one hour. which uses the most energy in that time?   the answer is: a toaster

As we have four different equipment then for house hold system we know the default power of all

Coffee maker = 1400 W

Vacuum Cleaner = 700 W

Toaster = 1800 W

Electric Drill = 1000 W

now the energy consumed will be given as

here time is same for all that is for 1 hour we used all components

so here maximum energy will be consumed by the component which will have maximum power

So answer must be Toaster which is having maximum power of 1800 W
