The division line between conductors, resistors and insulators is a bit fuzzyHere is my interpretation Porcelain I Ceramic I Lead C Wood I Cardboard I Chalk I Styrofoam I Fabric I Copper C Aluminium C Zinc C Plastic I Iron C Paper I Nickel C Rubber I Carbon C or R Silicon I or R depends on purity and additives Graphite C or R Carbon ( graphite) are used to make resistors, but that is because they are conductors with a relatively high resistance.
