from bound electrons in that they can be moved readily from their orbit.
If a point that has an excess of electrons (negative) is connected to a
point that has a shortage of electrons (positive), a flow of electrons
(electrical current) will flow through the connector (conductor) until an
equal electric charge exists between the two points.
c. Electron Theory of Electricity. A charge of electricity is formed
when numerous electrons break free of their atoms and gather in one area
(see figure 2). When the electrons begin to move in one direction (as along
a wire, for example), the effect is a flow of electricity, an electric
Actually, electric generators and batteries could be called
electron pumps, because they remove electrons from one part of an electric
For example, a generator takes electrons away from the positive
terminal and concentrates
