Creating Circuts With Graphite (with Pictures) - …
Why it Works: Graphite, although a poor conductor, is still a conductor, thus has the ability to conduct electricity. Its most common use (that involves electricity) is in resistors, which is why its ability to conduct electricity drops greatly the longer the line is. P.S.
