An . incandescent light bulb. is an electric light bulb that passes . electric current. through a . Tin Foi. l . Phonograph. The first great invention developed by Thomas Edison in Menlo Park was the tin foil phonograph. While working to improve the efficiency of a telegraph transmitter, he noted that the tape of the machine gave off a noise resembling spoken words when played at a high speed. This caused him to wonder if he could record a telephone message. He began experimenting with the diaphragm of a telephone receiver by attaching a needle to it. He reasoned that the needle could prick paper tape to record a message. His experiments led him to try a stylus on a tinfoil cylinder, which, to his great surprise, played back the short message he recorded. . 1. 0. .1 . What is Light?.

(Explain using what you have learned this week about charges – don’t just say “static electricity.”) Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . the word energy?. What do we need energy for?. What do you think we can do to get the flashlight to work?. What kind of action did you observe when the flashlight worked?. Actions occur only when energy is available to make them happen. What kind of energy produced the flashlight action?.
