Series and Parallel Circuits

A parallel circuit has multiple pathways between its beginning and end, which means it has more than one path to take. This enables it to use one path if another fails. Since they are so fail resistant, parallel circuits are used in everyday electronics such as household wiring.

A series circuit has only one path source through all of the loads and back to the source. An example of a series circuit are christmas lights since they must rap around an entire house. series_Circuit

Dryer Sheets

Dryer sheets help prevent static electricity caused by fabrics tumbling in a dryer. This static charge is built up where clothes rub together. The rubbing can knock loose electrons from some fabrics onto others. So while some fabrics may have many electrons, others could have more protons, causing them to attract to one another. Dryer sheets are naturally positively charged and provide a lubricating effect after they coat the clothing. By lubricating the clothing, friction is significantly reduced, which reduces the bonding/separating frequency that is causing the static charge to build up.  Thus, dryer sheets are typically impregnated with a heat activated, waxy substance which works as a fabric softener and coats the clothing with a very thin layer of lubrication, reducing friction and static charge buildup.

Remote Control

UnknownThe electronic I chose is a remote control. Depending on which button you press, different signals are sent to the television. I believe this is due some sort of identical wiring that is located in the cable box. This is why it is called an electronic. The electric currents that are exchanged between the remote and the television are what enables channels to change and other remote control functions. Although this is solely a prediction, I am still very puzzled about how the remote and television communicate.
