With the help of other sources, I now know that 3 9V batteries will do.But I would also like to know approximately how much time will be taken.
Can anyone help me?
For a school project, I need to electroplate copper on an iron nail with copper sulphate solution.
How much voltage electricity will I need for this experiment?

I have a serial light whose plug is not working. Its output is 2.5A 250v. I have spare plugs of 5A 250v. Is it safe to replace the former with the latter? If not, can you give any other suggestions?
