So as not to hijack the thread on current direction, this is a chance to follow up on nsaspook's comment about the speed of electricity.
I've always thought that electricity is a wave motion, caused by the rapid movement of electrons from one atom to another, and therefore the 'speed' of that wave is pretty much the speed of light. Whereas the speed of an individual electron passing from one atom to the next to the next will be much slower - roughly a metre per hour and is referred to as the drift..
So what's the real story? What is the speed of electricity and of individual electrons moving around a circuit? I guess it's not that straightforward?...what is really going on when you connect up a battery?
