WebGraphite is more conductive than clay, as the concentration of clay in the pencil’s resistor increases, the resistance increases. Clay compared to graphite is an insulator and does not conduct with electricity well blocking the flow of electrons. This shows that a 2B would be more conductive than a HB as it contains more graphite than clay. Method
