Why doesn't a line drawn by a pencil conduct electricity even though it is graphite?
I was wondering why a line drawn by a pencil doesn't conduct electricity, even though it is made of graphite.
Ah, that's an interesting question. Graphite is actually a good conductor of electricity, so it's strange that a line drawn by a pencil doesn't conduct. The reason why is because the graphite in a pencil lead is mixed with clay and other binders. This mixture makes the graphite less conductive.
