Do you remember how AC current works?
Last Tuesday in the Technology lesson we experienced how hard the life of the electron is.
I think it was Iliane who asked about light bulbs. In this video you can see how a light bulb works in slow motion. Notice how the light intensity changes as the electrons move in one direction, then stop and move in the other.
Do you believe me now? :-)
