摘要:

The note discusses electrical power and energy and includes possible labs to be used in a physics classroom. It is based on our experimentation with a new device called the Watt-Watt/Hour Meter, which displays instantaneous power and cumulative energy readings of household electrical devices. Our experiments utilized this meter in conjunction with various appliances and focused primarily on its use with a refrigerator.
