For my physic’s blog post this week, I took a picture of my phone because in class today we learned about circuits and the two types; DC and AC circuits. My phone is an example of a DC circuit because when I’m charging my phone, the charges are only going one way…to my phone. My phone isn’t transferring charges back to the wall through the charger because it just doesn’t work like that. An example of an AC circuit would be the Apple computer charger. I think one of the most important things I learned today is that energy transfers instantaneously, but the charges do not. This is referred to “drift velocity”.
