Graphite rod and conduction

TDIY-0001

Non metal is bad conductor of electricity but graphite conduct electricity inspite of being a non metal. How?
  • PENCILS GRAPHITE
  • LEDS .9 MM
  • ERASER
  • PAPER A4
Take the papersheet and draw pencil line. Complete the circuit using pencil line, LED and battery. Now see if the pencil line is able to conduct the electricity as done in the video. Now draw the lines of different length and different thickness and see how the brightness of the LED gets affected.
