Man, someone asking a basic question gets this type of "I know so much more than you can ever ask for" treatment
. He just needed a straight answer and he got it already.
You're both crazy imaginary!
IF the light bulb is indeed very high in wattage, rare in household (because it causes fire like you described) but just say you have one of those, the socket that connects to the bulb must have thicker wires and has a special plug that won't go in your household outlets unless it's put together by some brain-dead electrician. Your assumption although valid in math, again won't help someone trying to get a straight answer to a simple question and won't go very far in reality. Engineers make sure proper wire gauges are used on devices so that the devices, not their wires, get the most power. How come my car jumper cables are thicker than my breadboard jumper wires? You tell me. You can't assume they are the same size and you attach a huge wattage light bulb on a breadboard jumper wire and see who's getting most of the juice. But that was what you did. My 30W soldering iron has 500ohm resistance, with 120V voltage, it is about 30W. I guess most of the power is on the iron, since the wire is only lukewarm at best when the iron is operating. The engineers designed the right gauge of wires so wires don't count, not in my approximation.
BTW, if you really have 0.1ohm load and run it on 120V then you should prepare to pay for 144KWh each hour, if you get all the wiring properly. Although I don't own a house, I think larger appliances have their special outlets and larger circuit breakers, but nothing household has that large requirement of power.
This type of answers is too intimidating to beginners and becomes silly. Could we stop it?
