I asked because I have been arguing with a friend of mine for good half an hour that it CANNOT use more because the resistors do guard from more voltage to getting through. It can use less though, due to other poor components...
And we were not talking about malfunctions either, his argument was simply "the instructions and manuals are bull****, it uses more than they say it does." He couldn't offer any better argument, that's why I kept to my, not too confident, rationalization about why and how it is.
So... Basically, it can use more electricity if there is a malfunction, it can use less due to poor parts, and it can use a little more due to voltage fluctuation. Is that correct?
