Electric Potential

So this week (if today counts) we learned about electric potential energy and electric potential. First off, DO NOT GET THESE CONFUSED. Or else Da Freitas will come and eat you. Just kidding, he'll probably play you a song. Anyhoo, electric potential energy is basically another type of energy that falls in the stored energy bracket with its friends "gravitational" and "spring." To define it in a "proper manner," it is the stored potential energy of a charged object in an electric potential field. That means JOULES are your choice of unit! However, pleasepleaseplease do NOT get this confused with ELECTRIC POTENTIAL units, which are volts (aka joules per unit of charge). That makes the relationship between electric potential and electric potential energy similar to power and work, in that the latter for each relationship is just a smaller part of the first.
Now, I have a photo of the plug in the Concert Glee room where I am typing this out because we talked a lot about volts in class today. If you touch a plug like the one in the photo, you will more or less be shocked. Duh. But guess what? It's the amount of charge coming out of the plug that hurts you, not the 120 V flowing through. So, the next time you get shocked (WHY??? You're supposed to be mature/old enough to not do that...), at least you know it's the charge! :)
