Resistivity and resistance. Permittivity and?
Look at the unit analysis: Resistivity is measured in &Omega;-m. When you mutliply by length (m) and divide by area (m2), you're left with just &Omega;.

Permittivity is measured in Farads/m. When you multiply by area (m2) and divide by spacing (m), you're left with just Farads, or capacitance.
