What is the density of conduction electrons in copper wire? Give your answer in cm—3. Look up the density of copper and its atomic weight, and imagine that there is one conduction electron per atom (ie, all the other electrons are bound to the nuclei). A good car battery can put out about 250 A h of total charge at 12 V. If you simply short—out your car battery with a copper wire of diameter 5 mm, how far does a typical conduction electron move in the wire? Don't do the experiment! It's incredibly dangerous.
