electric charge |
Electric charge is a physical property of particles or objects that causes them to attract or repel each other without touching. |
|
|
electric field |
An electric field is 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 is called electric force. |
|
|
law of conservation of charge |
Electrons move, but they aren’t destroyed. |
|
|
static discharge |
This sudden flow of electrons. |
|
|
static electricity |
the buildup of charges. |
|
|
alternating current |
When current keeps reversing direction. |
|
|
direct current |
When current flows in just one direction. |
|
|
electric conductor |
Materials that have low resistance to electric current |
|
|
electric current |
The flow of an electric charge |
|
|
electric insulator |
Materials that have high resistance to electric current. |
|
|
Ohm’s law |
The relationships between current, voltage, and resistance. |
|
|
resistance |
Resistance, on the other hand, opposes the flow of electric current. |
|
|
voltage |
The difference in electric potential energy is called potential difference, or voltage |
|
|
electric circuit |
A closed loop through which current can flow is called an electric circuit. |
|
|
electric power |
The rate at which a device changes electric current to another form of energy is calledelectric power. |
|
|
parallel circuit |
A parallel circuit has two (or more) loops through which current can flow. |
|
|
series circuit |
if one light bulb burns out the other light bulb will not work because it won’t receive any current because it is all on circuit. |
|
|
electronics |
The use of electric current to encode information is called electronics. |
|
|
semiconductor |
A semiconductor is a solid crystal—usually consisting mainly of silicon—that can conduct current better than an electric insulator but not as well as an electric conductor. |
