static electricity build up of electric charge on an object
electrical conductor a material through which charges can move freely
electrical isulator a material through which charges cannot move easily
semiconductor special class of material that conduct electric charge better than electrical insulators but not as well as electrical conductors
electrical curent rate of flow of electric charge
voltage the amount of work required to move each unit of charge between two points
resistance opposition to the flow electric charge
electric circut a complete, closed path through which electric charges can flow
series circut all parts are connected in a row that forms one path for the electric charges to follow
parallel circut electric charges have more than one path that they can follow
magnet used to describe any material that attracts iron or objects made of iron
magnetic force exert a push or a pull when 2 magnets are close together
