Sorry Koneg, but you are wrong.
Well then maybe you can explain why it is that electrical companies bill you by the number of Watts you use?
Because clearly, if you were using a 1,200,000,000,000 volt circuit instead of a 120 volt circuit they'd want to charge you more, because it's using more electricity, right?
So how come they don't?
(Note: These questions are rhetorical and strictly for my amusement. I already know you can't answer them correctly)
You are correct as far as you go..... BUT you are leaving the transformer out of the equation.
Lets look at Paul's electrical scenario again....

Suppose I have 2 lights. One is 12 volts / 20 watts. The other is 120 volts / 20 watts.

But he doesn't leave it there, he throws in some more components/variables to this puzzle.

Both run off of a regular electrical outlet.
Paul is stating that both will be running off regular outlet, a regular out let in the USA is 120v. Only one of the two light bulb circuits that Paul states is capable of being plugged directly in to the 120v regular outlet.
So for the 12v / 20w circuit to work, and not let the manufacturers smoke out, you will OBVIOUSLY...

Obviously the 12/20 one has something internal to the light that converts from 120 volts to 12.
"Internal to the light" meaning the 12v /20w circuit will be needing a transformer, because a 12v circuit can't handle the 120v regular outlet.
Thus, adding another load onto the circuit of the 12v /20w light bulb.

My question is,
do they consume the same amount of electricity?

So it should be Obvious that the 12v /20w circuit will consume more.
I guess it could be argued what "do they" is referring too, but in how he lined out the scenario I think it is obvious that he is talking about the two different 20 watt light bulb circuits.
