    In comparisons to electrical sockets from US and UK, the UK electrical sockets are way more safer than the US sockets by far. It's a somewhat perfect design for complete safety, meaning you won't get an electro shock from turning a switch on or off. In addition to these safety measures you also get socket covers to put over the electrical outputs to prevent kids or anything from getting in there and trying to electrocute themselves. I say UK plugs are the best of their design because each and every appliance carries their own fuse so they don't trip the circuit breaker, its cheaper and more efficient that most appliances sold in other countries that don't employ the same kind of setup in their appliances. Because if the fuse happens to break, you can just take it out and replace it in that appliance by pulling the little plastic tab that you see on the plugs themselves to reveal a pill sized fuse, buying a small pack of fuses from your local hardware store is about as cheap as ₤5. If you try to plugin an appliance without a fuse in them they simply will not turn on.

    In addition to other safety measures for electrical sockets, if you take a UK power strip you can't electrocute yourself because of a safety prong keeps the shutters closed, and also prevents people from sticking their fingers in there and electrocuting themselves. So long as the top prong, the earthed prong of a plug is inserted as it goes into the socket it will safely unlock the shutters so the plug can make a connection , and you can hear a solid click sound as you insert a plug, and thats the sound of the safety shutters opening and closing.

    For 240v connections for welders/plasma cutters or other machines, the switches are usually called hammers because the "click" is closed to bashing a hammer on a metal table.

    I worked for 7 years for a power company, 3 different departments, the transmission part, with power lines and glass, silicon insulators, the operation part with substations and big breakers with oil, and the protection department with the little relay to coordinate why street circuits automatically turn back on, or not. BTW huge 230kV breakers use compressed air to blow away the voltaic arc inside the switch part, so they open the circuit internally, with SF6 and a blow of air, then externally. I can tell, the land shakes with a loud boom when they are operated.

    Mercury switches - no click and no arc. They should be good for 4 more minutes! Of course there also are switches which are more likely to produce an "ouch" sound.

      @Kadiea Navales
      1) USGS is the one who said distilled water was pure. According to you, that's a more reputable resource than wikipedia.
      2) Pure water has ions in it. You're thinking of deionized water.
      3) Deionized water ALSO has a dialectric strength, and therefor a breakdown voltage where current will flow.
      4) Electricity can flow through empty space. It does not require a medium, much less one with ions.

      And stop telling me I don't know how electricity works when you don't even understand dialectric strength. I have a combined EE/Physics degree.

    • Kadiea Navales
      Kadiea Navales 18 hours ago

      @Falcrist I don't think you understand how electricity works. For one you're under the false assumption that distilled water is pure water as that's what all your links are referring to. Electricity can only flow when there's a flow of electrons or ions present in the medium. Pure water doesn't have electrolytic substances and neither hydrogen or oxygen have d or f orbitals in which electrons may pass through. Maybe if YOU read a textbook you'd understand that basic concept that distilled water ISN'T pure water

    • Falcrist
      Falcrist 19 hours ago

      Or you could google "Dialectric strength of pure water"

    • Falcrist
      Falcrist 19 hours ago

      @Kadiea Navales I mean... you could open a textbook too, but I'm certainly not going to assume you have one of those.
      If you don't like wikipedia, check out the "CRC Handbook of Chemistry and Physics".
      And going by USGS, distilled water is considered "pure":

      "Water that would be considered "pure" would be distilled water (water condensed from steam) and deionized water (used in laboratories)"

    Some older trams like Czechoslovakian Tatra T3 / T3SU(CS) have line contactor, that makes noticeable clack sound when turning on and even louder when breaking higher current (60 - 540A (750 A max when overcurrent trips contactor instantly) at 600 V DC). Newer trams are fully solid state but still have line contactor as backup beacuse lowering pantograph under overcurrent would cause huge electric arc

    so my brain went "that bright thing makes this smell, so let's pretend we smell that"
    It stopped when you stopped playing with the plug.

    Also when you break of an inductive load the voltage across will rise momentarily and the arch jump more easily.
    The voltage across an inductor follows this equation v=L * di/dt which shows that the current through cant change instantaneously and therefore will compensate with higher voltage because of the large di/dt

    wait... dont they switch polarity every 60hz?
    "oscillations of alternating current (AC) in an electric power grid transmitted from a power .... As the 20th century continued, more power was produced at 60 Hz (North America)"... not 100-120. you were talking about 100-120volts...
