Moderate# Pencil Lead Conductors

APPH12-YVRZKZ

A student connects one end of a battery to an ammeter and keeps the two remaining electrical leads open to perform tests of conductivity on various objects. The student tests two lengths of graphite by using unsharpened pencils with their erasers cut off. The first pencil is twice as long as the second pencil.

Which pencil will produce larger current in the ammeter and why?
