Q:

What is electrolysis, its cause, correction?
A: Electrolysis is the flow of electricity caused by the difference in potential of two dissimilar metals immersed in electrolyte. It acts as a plating process and one metal is eaten up and deposited on the other. Prevent harm to underwater parts by attaching sacrificial anodes (usually zinc). Replace from time to time as they deteriorate.
