Electricity

electricity

the presence of flow of electrons

static electricity

a buildup of charges on an object

current electricity

constant flow of electric charges

protons

positive electric charge

Electrons

negative electric charge

Neutrons

neutral charge

Friction

rubbing an object on another, causing electrons to transfer

Induction

a charged object comes close to another, causing electrons to rearrange

electron affinity

a substance's ability to hold onto electrons

attraction

opposite charges attract

repulsion

same charges repel

electrical circuit

pathway that electric current follows

conductors

electrons move easily

2 examples of conductors

copper and metals

Insulators

electrons do not move easily

Semiconductors

behave as insulators or conductors

Voltage

pushes the electrons

current

the flow of electrons

Resistance

anything that resists the flow of electrons

Power

how quickly electricity is used

closed circuit

pathway of the electrical current is complete

Open Circuit

pathway of the electrical current is broken

Series Circuit

one pathway

Parallel Circuit

multiple pathways

Ohm's Law

mathematical relationship between voltage, current, and resistance
