Define area effect regarding galvanic corrosion?

Define area effect regarding galvanic corrosion? Correct Answer cathodic area/anodic area

It is the ratio of cathodic to anodic areas. An unfavorable area ratio with a large cathodic area and small anodic area results in high current density at the anode. The greater the current density at an anodic area the greater the corrosion rate.
