|How do you calculate electric power?
|power=voltage x current
|rate at which energy is transformed from one form to annother/ unit is the watt
|How do you calculate electric energy
|energy=power x time
|unit of electric energy / kilowatt x hours
|How can electric shocks be prevented?
|shocks can be prevented with devices that redirect current or break circuits
|is a connection that allows current to take the path of least resistance
|connect the circuits in a building directly to earth, giving charges an alternate path in an event of a short circuit
|connects any metal pieces in an appliance to the safety grounding wire of a building
|are devices that melt if they get too hot
|are switches that will bend away from circuits as they heat up / can reset
|any circuit connected to earths with a third prong
