|
Electric Charge |
A physical property of particles or objects that causes them to attract or repel each other without touching. |
|
|
Electric Field |
A space around a charged particle where the particle exerts electric force on other particles. |
|
|
Electric Force |
The force of attraction or repulsion between charged particles. |
|
|
Law of Conservation of Charge |
Electrons move, but they aren’t destroyed. |
|
|
Static Discharge |
A sudden flow of electrons. |
|
|
Static Electricity |
A buildup of charges on an object. |
|
|
Alternating Current (AC) |
Keeps reversing direction. |
|
|
Direct Current (DC) |
Flows in just one direction. |
|
|
Electric Conductor |
Materials with low resistance. |
|
|
Electric Current |
A continuous flow of electric charge. |
|
|
Electric Insulator |
Materials with high resistance. |
|
|
Ohm’s Law |
Current (amps)=Voltage (volts)/ Resistance (ohms) |
|
|
Resistance |
It opposes the flow of electric current. |
|
|
Voltage |
Voltage, is a difference in electric potential energy. |
|
|
Electric circuit |
A closed loop through which current can flow. |
|
|
Electric power |
The rate at which a device changes electric current to another form of energy. |
|
|
Parallel Circuit |
Two (or more) loops through which current can flow. |
|
|
Series Circuit |
Has only one loop through which current can flow. |
|
|
Electronics |
The use of electric current to encode information. |
|
|
Semiconductors |
A solid crystal consisting of mainly silicon that can conduct current better than an electric insulator but not as well as an electric conductor. |
