Answer:
An Iron ring can be coated into copper without electricity by galvanization.
Galvanization is the method to apply a protective coating of zinc to iron and steel.
This method prevents the rusting of iron and steel.
The most common process is galvanizing a hot-dip, in which the pieces are immersed in a bath of molten hot zinc. Thus, iron ring can be coated by galvanizing and does not needs electricity.
