What is the difference between a carbon electrode and a graphite electrode?(for electrolysis)?

Question

I know graphite is carbon, but any other differences? I read somthere that a carbon electrode uses less power. Is this true? In electrolysis, does one produce more H or O2 than the other or does one do it faster?

Answer 1

Carbon electrode are more porous & soft it will dissolve damage very fast, where as graphite is so harder it will not deform, it can carry more current long lasting than carbon.
