I am doing a science fair project on electricity. I am building a secret alarm system. I have information about it, but any more you could give me on why the alarm goes off when the switch goes down when you hit a trip wire would be very helpful. However, I do also need information on who invented or discovered electricity. Thank you so much. By the way, my sister has used this site many times and says it rox!! so thanx a lot in advance!:-)
