What The...?!

Photobucket As i was sitting on the toilet i noticed that one of the light bulbs was burnt out, but the others were still shining. Using my knowledge of parallel circuts it hit me. A parallel circut has more than one path for charges to flow through and has more than one resistor. In a parallel circut if one light bulb were to to be disconnected or burnt out it would not affect the other light bulbs. That is why many lights around the house are made of parallel circuts. Who knew?!!!

Electricity

Photobucket
As i looked at my Cd Player i was wondering why it was not turning on. I look at the back of it and i see that the battery is out of its socket. It reminded me of the principles of elctrical circuts. An Electrical cicut is any path along which electrons can flow. In order for their to be a electical current there must be no breaks on the elctrical path way. There are two types of pathways for elctrical circuts, seriers and parallel. Series has only one pathway for the electrons to flow. In parallel they have different pathways branching of in sepearate paths for elctrons to flow. If i were to push in the battery to fill the gap in the circut my Cd player will now be ready to play my music.
