One of the students from my last two office hours came asking for help with this weeks written work. I don't believe I saw such a problem last semester, though it may have slipped my mind. It asked for the electrical potential of a charged sphere inside and out of its radius. I ended up using the internet for help.

The rest of the online homework went smoothly. There isn't much you can do to trip someone up on electric potential, as there are no vectors. On that note, Dr. Hong posted the handout I created on courseweb. Hopefully, this will lead to less confusion.
