“I saw in an experiment that by placing the probes of a multimeter on the resistance scale, a low resistance was measured on a pencil. I did the experiment but nothing happened. Can you explain?"

 

Yes, the graphite of black pencil is conductive, but in the case of pencils of other colors graphite is not used, but another substance that is not conductive. Experiment with an ordinary black pencil.
