When a wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor. The moment contact is made, the free electrons of the conductor will drift toward the positive terminal under the influence of this field.

A thin, solid line (as shown above) is the conventional symbol for a continuous piece of wire. Since the wire is made of a conductive material, ... However, there will never be a continuous or uniform flow of electrons within this wire unless they have a place to come from and a place to go. Let's add an hypothetical...

Free electrons can be made to flow through a conducting wire, such as copper. A voltage source, such as a battery, is required to "push" the electrons in a steady flow. Electricity in motion like this is called current electricity.
