Battery Circuit Conductor A source of electrical energy A path along which electric current flows Material through which electric current passes easily Example: copper wire Electric Charge Can be positive or negative Filament A small coiled wire that glows when electric current passes through it Insulator Material through which electric current does NOT pass easily Examples: rubber or plastic Pole Resistance A place on a magnet where magnetism is strongest Measure of how well electric current flows through a material Switch Voltage Terminals Device used to stop and start the flow of electric current in a circuit Push needed to move electric charges The points where electric current leaves and enters a battery Static Electricity Examples: Lightning Cat’s fur sparking Fingers getting a shock when you touch a doorknob after rubbing your feet on carpet Repel To push away When the N poles on two magnets are near each other they will push away Attract To pull towards When the N poles on two magnets are away from each other they will pull towards each other Closed Circuit Parallel Circuit The only way electric current can flow through a circuit Electric current flows through more than one path Series Circuit The glow of a fluorescent light bulb is caused by a coating on the inside of a tube. All the circuit parts are connected one after the other
