Is your hair then positively or negatively charged? How about the comb? -The hair becomes positively charged and the comb becomes negatively charged; since‚ the electrons went from your hair to the comb and the more electrons there is makes an object more negative. 18)

I chose the Jacob’s Ladder as my Science Demo Project because I wanted to learn how the electrical current travels from the transformer and up the wires connected to the electrical source. The group currently consists of myself only. I chose to work alone because I did not want to worry about depending on others to complete the work‚ and I also wouldn’t have the trouble of lazy people just not even trying to complete it. Another reason why I chose to work alone on this project is so I wouldn’t have
