I don't want to know what it's like, I want to know what it IS.
On an unrelated note, I read this excerpt from a Hyperphysics article on voltage;
"Like mechanical potential energy, the zero of potential (of voltage) can be chosen at any point, so the difference in voltage is the quantity which is physically meaningful."
What does that mean? It's really bothering me.
