not true..read on this quote... i will paste the web site it is from below
To prevent the tank from rusting or your heater element from corroding, the brilliant plumbers and chemists of long ago created a sacrificial rod for the water heater tank. The idea was that the anode rod would corrode first, leaving the metal of the tank (and element if you have an electric water heater) alone - saving you from dealing with a rusty behemoth that randomly springs leaks. This works because the anode rod possesses a lower, more negative, electrochemical potential than that of the water heater's steel composition. The negatively charged electrons create a higher voltage to flow from the anode rod to the steel tank causing the anode rod to corrode instead of the steel water heater tank, or other exposed metals such as electric elements. The anode rod is "self-sacrificing" and will continue to corrode until eventually it must be replaced. When there's no sacrifical metal left on the anode, the tank can rust out - which is why it is so important to

the current is VERY weak but never the less it is there
