The current in a circuit is modeled as "the rate at which charge flows past a point on the circuit" (Electric Current). A voltage source drives this negative charge flow, or electricity since it is moving electrons.
Currently in the McArthur Theory for electronics we have a bunch of really depressed people who hate each other but all want to go to this sad concert. Now what really upsets them is that they have to get in their sad little cars, probably Toyota Prius's, and drive there. This movement of negative people from one place to another is the current. If they drive fast then the current is higher and if they drive slow it is lower.
