Presentation transcript:

 Phantom Load: The power used by something while turned off Another word for phantom load is standby power

 Watt: James Watt100 Watt Light Bulb A unit to measure power that is equal to one joule per second Named after James Watt

 Watt Hour: a unit of energy that is equal to 3600 joules or one watt working for one hour  Watt vs. Watt Hour An electric meter labeled by kilowatt hours (1000 watt hours)

 Joule: The equation to determine the number of joules a unit of energy that is equal to the force of one Newton through the distance of one meter

 Watt Meter: an instrument used for measuring electricity in watts The watt meter that we used

 Energy: Electrical Energy Solar Energy Potential Energy the ability to do work

 Energy Efficiency: the amount of useful energy available after a conversion occurs Energy star appliances are examples of energy efficient appliances

 Energy Conversion: Example: Solar panels convert solar energy to electrical energy changing energy from one form to another
