When I first replied, there was a problem statement about an electrical appliance that consumes 800 W when connected to a 120 V outlet in Canada. The question was how much power it would consume in the UK where the outlets are 240 V. There were five choices, all in kW, which I don't remember except for the correct one which can be easily reconstructed and "zero" which means that Canadian appliances in the UK would be useless.

It seems that OP replaced the statement of the problem with "nevermind", but the post was not stamped as having been edited. Oh well.

Yeah, he edited it right away, so there is no "History" link in his post that I can see. Thread is closed.
