I have a question about electricity. In Europe, an electrical power plug has two "sticks" or whatever you call them. I understand here that power comes in through one of them - goes through the apparatus - and out the other stick. This makes sense. This is a so called "one-phase" system. What does "one-phase" actually mean? Three-phase systems have three "sticks" I know, so how does the power flow here? Help!
