electricity | the movement of electrons from one atom to another |
electric circuit | the path electricity takes |
closed circuit | type of circuit that makes a complete circle and allows electricity to flow |
open circuit | a type of circuit where there is at least one break that does not allow electricity to flow |
The largest magnet on Earth is | Earth |
series circuit | a circuit that has only 1 path |
parallel circuit | a circuit with 2 or more paths |
atoms | the smallest bits of a pure element |
proton | atomic particle with a positive charge |
neutron | atomic particle found in the nucleus with no charge |
electron | atomic particle that orbits the nucleus and has a negative charge |
charge | a property of matter where atoms become positive or negative due to the loss or gain of electrons |
static electricity | a type of electricity caused by the build up of negative charges in one place and positive charges in another |
electric current | the flow of electricity through a material |
insulators | materials that do not let electric current flow |
conductors | materials that allow the flow of electricity |
direct current | current flows in one direction |
alternating current | current can move back and forth in either direction |
volts | measurement of the "push" to get current flowing |
amps | measurement of the amount of electricity flowing through a circuit |
watts | measures how much electricity is used |
magnet | metals that have their atoms lined up |
