A B CIf bulb A burns out, which bulbs will light? Bulb B Bulb C Bulb B C No bulbs In the above circuit if two more bulbs are added to the circuit. what will happen to the brightness of the bulb? brightness will decrease brightness will increase no change Vocabulary Match the vocabulary word with the definition series circuit if one bulb goes out, all the bulbs goes out parallel circuit if one bulb goes out, the rest of the bulbs stay on complete path allows electricity to flow through resistor controls the flow of electrons switch opens and closes a circuit static electricity sudden discharge of electricity, usually jumping to the closest object Electric Circuit In the above circuit, how could you make an incomplete path? it is already incomplete turn the switch on Turn the switch off In the above circuit, what would happen if you turned one of the batteries the other way ?(where both gold sections of the batteries were touching) no change no bulbs would light bulbs would burn brighter In the above circuit, what would happen if another battery were placed on the yellow section of the wire? no change no bulbs would light bulbs would burn brighter Determine which items are electrical conductors and which are electrical insulators. conductors Copper Aluminum gold silver insulators glass air plastic rubber ElectromagnetsFill in the words to make the statements correct. An electromagnet consists of a length of conductive wire, usually copper, wrapped around a piece of metal. A current is introduced, either from a batteryor another source of electricity, and flows through the wire. This creates a magneticfield around the coiled wire, magnetizing the metal as if it were a permanent magnet. Electromagnets are useful because you can turn the magnet on and off by completing or interrupting the circuit, respectively. You can make an electromagnet stronger by wrapping around morewire.
