The system resistance is in large part dictated by the environment and not easily changed. Higher Current Systems. The basic formula for a DC circuit is that V = I x R (Ohm’s law) where V is the voltage difference or driving force, I is the system current and R is the system resistance. Today’s most efficient anodes are the dimensionally stable mixed metal oxide anodes (MMO.) These anodes have exceptionally long anode life relative to other anode choices.
