Term | Definition |
---|---|
How is electric current made? | when electric charges are made to flow through a material they provide an electric current |
Electric Circuit | a compete, unbroken path that charges can flow through |
What affects current flow? | current flow is effected by energy of the properties of the objects that charges flow through |
Voltage | the difference in electric potential energy per charge between two points in a circuit |
The more resistance = | less current |
How do you calculate electric power? | power= voltage x current |
Power | the rate at which energy is transformed from one form to another |
Field Line | shows the force that would be exerted on a positive charge at any point along that line |
Electric Force | the force between charged objects |
What do single charges have? | straight field lines |
Static Electricity | buildup of charges on an object |
Polarization | the electrons react to electric fields resulting in individual atoms having charged ends that are attracted to charged objectives |
Electric Potential Energy | the differences causes charges to flow through wires |
Properites of an object | affect current flow |
Conducting Wires | the path of current in a circuit is completed by these |
Is energy always lost in a circuit? | no, energy is conserved |
Do objects have some overall charge? | no, objects have no overall charge |
Grounded | a circuit connected to earth with a three-pronged plug |
