ELECTRICAL CIRCUITS: Power Hungry

Try it! Our circuit has a 6-volt battery, pushing 2 amps of current through.

[Interactive: 6 volts x 2 amps = ______ watts]

Twelve watts of power is enough to make a flashlight bulb glow brightly, but it won't do much at all for a regular light bulb, which consumes 40 to 100 watts of power, or for the average computer (200 watts), toaster (900 watts), or microwave oven (1200 watts). That's why most homes, schools, and businesses rely on the higher voltage electrical energy that is made and delivered by a power plant.
