Sacrificial Anode
... The voltage that we found for the sacrificial anode was -0.063V. Therefore, iron will not act as a good sacrificial anode for iron, but if a material had a galvanic potential less than the opposite of that voltage, it would successfully protect the object from corroding. When we placed iron in the g ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
