Electricity usage of light bulbs
Would it use more electricity to leave a main light on - 100W, 240V - or to leave a 12W lamp plugged into a 240V socket? I know it looks like a simple matter, but I wondered if the different wattage actually made a difference. The lamp actually said it was 12W and 20V but I guess that 240V is still coming out of the wall; it just gets cut out in the plug.
