electrical insulator a material through which charges cannot move easily
semiconductor a special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors
electric current the rate of flow of electric charges
voltage the amount of work required to move each unit of charge between two points
resistance the opposition to the flow of electric charge
electric circuit a complete closed path through which electric charges can flow
series circuit all parts are connected in a row that forms one path for the electric charges to follow
parallel circuit electric charges have more than one path that they can follow
magnet any material that attracts iron or objects made of iron
magnetic force when you bring two magnets together they exert a push or pull
