This whole unit we have been learning for the past couple weeks was about electricity. Recently we learned that our houses have mostly parallel set ups. This is because if we had series set ups, we wouldnt be able to run as much electronics off of one circut without crashing it. With parallel set ups, each outlet in the house will get a certain amount of voltage no matter what. This picture is of my computer charger. There are three three prongs. The long round prong is a ground prong. This is one of the things i learned that stuck in my head this week.
