Graphite Conductor

Connect a torch bulb with a battery by means of a pair of scissors and a pencil. The bulb lights up.From the long tongue of the battery, the negative pole,the current flows through the metal of the scissors to the lamp. It makes it glow, and flows through the graphite shaft to the positive pole of the battery. Therefore graphite is a good conductor so much electricity flows even through a pencil lead on paper, that you can hear crackling in earphones.
