AC/DC
Electricity can flow in either
direction. If it only moves in one direction, it is called
Direct Current (DC). Remember the idea expressed earlier
that as electricity flows it also makes a magnetic field?
Well if you spin a bunch of wires between two magnets,
(which you might do with, say a waterwheel) you get electricity
that swings back and forth between positive and negative
charges creating Alternating Current (AC).
