Electrical Power

How is power related to energy? What determines the power rating of a device? Electrical devices are commonly rated in units of power, such as a 100-W light bulb or a 1200-W microwave. The electric company bills homes in units of energy. Why the difference? In this investigation you will build circuits containing two different resistors in series and parallel (representing two different electrical devices) and measure the power and energy output of each device for each circuit.
