When you made the table of the ratings of various household devices, there were a number of boxes you had to leave empty because either the power or the current rating was not given.
But now you can fill in the blanks -- for example, the
computer monitor uses 1.8 Amperes x 110 V = 200 Watts. Add a few
more electrical items to your list -- a light bulb, a radio, a
coffee pot, ... so that we get an idea what is going on in those
wires around the house.
(You can print a new blank table if you like).
Filling in your blanks in the table is more than a math exercise, or a reinforcment of the idea that power = current x voltage -- you also learn how much power different devices use. To put the results into an everyday context, note that if you draw 1000 W for 1 hour (1 kilowatt-hour of energy), you owe the power company about $0.10 (less in Kentucky, where there is lots of coal).
