It does not readily accept or give up electrons.
OooooooooPs. I guess our program on dynamic electricity wasn't as good as we thought.
The question was - the reason a material is a good conductor is because: Do you remember the illustration
with the pipe and the ping pong balls?
If you were to push another ball into one end of the pipe, it would cause one to pop out a the opposite end. This is
exactly what happens in a conductor. When an electron is forced into one end of a conductor, an electron pops
out the opposite end. Not the same electron of course, but the result is the same. You put an electron in at one
end and get one out at the other end. Now the easier a material will accept and give up these electrons, the better
conductor it makes. OK? Now, let's go back to Page 1-1A and try the other answer.
To provide a force to move the electrons around the circuit.
Now you know better than that. There are three things required to complete an electrical circuit. They
are a source of electrons, a conductor or "path" for the electrons to travel around the circuit, and a force to push
the electrons through the conductor. Remember, back in the lesson on dynamic electricity, we said we had a force
to push the electrons through the circuit. It was called EMF (electromotive force) and it was supplied by a battery
or a similar device. Now go back to Page 1-4A and read the question again.
