|
Electron |
part of an atom that has a negative charge |
|
|
Ion |
a positivley or negatively charged atom |
|
|
Static charge |
imbalance of electric charge on an object |
|
|
electric force |
force between objects (exerted upon each other) |
|
|
electric field |
when electric forces exert a force on each other at a distance |
|
|
insulator |
a material that electrons can't move easily through; does not conduct electricity |
|
|
conductor |
materials in which electrons can move easily through; conducts electricity |
|
|
electric discharge |
rapid movement of excess charge from one place to another |
|
|
grounding |
providing a pathway to get rid of excess charge back to the earth/ground |
|
|
Electric current |
flow of electric charge; steady flow of electrons |
|
|
circuit |
loop in which electric charges will flow continuously |
|
|
open circuit |
circuit in which electricity can't flow (there's a break in the look; not complete) |
|
|
closed circuit |
circuit in which electricity can't flow (loop is complete) |
|
|
resistance |
a measure of how difficult it is for electrons to flow through a material |
|
|
parallel circuit |
a circuit that has more than 1 path for the electricity to flow |
|
|
series circuit |
a circuit that has only 1 path for the electricity to flow |
|
|
repel |
to move away from |
|
|
Ohm's Law |
current=voltage/resistance (voltage divided by resistance equals electrical current) |
|
|
Ohms |
the measure of resistance |
|
|
ampere |
the measure of the flow of electric charge or current |
|
|
volt |
measure of the force that the electrons have going through the wire |
|
|
battery |
device that changes chemical energy into electrical energy |
