Product Analysis. Lab 3. Product Analysis Objectives. Combine previous lab experiences to better understand the workings of a completed product. Develop an appreciation for horsepower and wattage considerations in product design.
watt [for James Watt], abbr. W, unit of power, or work done per unit time, equal to 1 joule per second. It is used as a measure of electrical and mechanical power. One watt is the amount of power that is delivered to a component of an electric circuit when a current of 1 ampere flows through the component and a voltage of 1 volt exists across it.
horsepower, unit of power in the English system of
units. It is equal to 33,000 foot-pounds per
