EXERCISE 1.
Appliances are labeled with the amount of watts they use. Look on the back or on the bottom at each of the prepared stations. Not all labels are in watts, some are in volts and amps. Volts and amps are related to watts: watts = volts x amps. Record either the watt or volts/amps in the space below.
