Question | Answer |
A metal rod about 20 cm (8 in.) long, is attached to the highest point of a building and protects the building when lightning strikes. | Lightning Rod |
A continuous flow of electric charges. | Electric Current |
An electric circuit in which the parts are connected in a single path. | Series Circut |
The electrical property of particles of matter; can be positive or negative. | Electric Charge |
A device that completes or breaks the path a current can follow in an electric circuit. | Switch |
The loss or release of an electric charge. | Electric Discharge |
A material through which electricity moves easily. Copper is an example of this. | Conductor |
Contains a filament that glows when electricity passes through it. The contacts at the base conduct electricity. Produces two forms or energy. | Incandescent Bulb |
Electric charges that have built up on the surface of an object. | Static Electricity |
When negative charges jump from a cloud to the ground this occurs. | Lightning |
A path along which an electric current can move. | Electric Circuit |
An electric circuit having more than one path along which electric current can travel. | Parallel Circuit |
Electric charges bump into particles of mercury gas. The gas gives off ultraviolet light. The light strikes the coating, which gives off white light. | Florescent Bulb |
Invented the light bulb. | Thomas Edison |
A switch that opens or closes a circuit by turning off or on. | Circut Breaker |
A material through which electricty does not move easily, rubber is one example. | Insulator |
A long, thin coil of wire that glows when electricity passes through it. | Filament |
A device in a circuit that contains a metal strip, which melts when the circuit is overheated, thus breaking the circuit. | Fuse |
