CONDUCTORS, RESISTORS, INSULATORS, AND COLOR CODES
So far in your study of dynamic electricity and Ohm's law, you have learned that three things are
necessary to complete an electrical circuit. They are a source of electrons, a conductor or "path" for the electrons
to move along, and an EMF or "force" to push the electrons along the conductor.
At this time, we are mainly interested in the material that acts as a path for the electrons, or as it is called
in electrical circuits, the conductor.
A conductor is a material that offers small opposition to the flow of electrons.
Now, let's go back for a moment and see what you remember from the lesson on dynamic electricity.
The reason a material is a good conductor is because:
its atoms can easily accept and give up electrons.

it does not readily accept or give up electrons.

YOUR ANSWER:
To supply a source of free electrons.
(From P1-4A)
Sorry, bad guess. Remember, there were three things necessary to complete an electrical circuit. They
were a source of electrons, a conductor or "path" for the electrons to move along, and a force to push the electrons
through the conductor. Now, go back to Page 1-4A and try again.
