  • North America uses 120 V for most circuits. Power is the product of voltage and current.

    At 1 Amp, 120 watts are dissipated by the circuit. About the heat of two incandescent light bulbs.

    At 10 Amps, 1200 watts are dissipated by the circuit, about the heat of a space heater.

    At 551 Amps, 66,000 watts are dissipated by the circuit. I don’t even have a good comparison. That’s like the power draw of 50 homes all at once.

    The higher the gauge, the lower the diameter of the wire. The lower the diameter of the wire, the more of that 66,000 watts is going to be dissipated by the wire itself instead of the load where it is desired. At 22 gauge, basically all of it will be dissipated by the wire, at least for the first fraction of a second before the wire vaporizes in a small explosion.

    EDIT: In this scenario, the total resistance of the circuit must be at most 0.22 Ω. Otherwise, the current will not reach 551 A due to Ohm’s Law, V=I×R. This resistance corresponds to a maximum length of 13 feet for copper wire and no load.

    If somebody you follow doesn’t boost or reply to a post, it will never cross your timeline unless you follow one of the hashtags contained in a post. So including hashtags is realistically the only way to reach people more than a couple degrees of separation away.

    I watched a video of a Linux noob trying it for the first time. They chose Mint, and a significant amount of problems arose from the fact that mint is still on an old kernel version, and there was little to no indication from the OS or from cursory googling that updating it would fix the issue or even that you should do that.
