In the US for example the standard is 110V for voltage and 80psi for water. In Europe, voltage is 220V, is water pressure different there too?

    Is that substantial though or is it like calling 120V something like 110V/115V?

      It doesn’t matter one bit. The actual voltage from the wall varies, and devices are build to operate under a fairly wide margin.

      Hes just being pedantic. Reality is US houses get a +120v and a -120v supply. Combine them is how you get 240v.

        There’s lots of pedantry going on in this thread rather than attempting to understand the spirit of the question.

        sorry dude thats not right. first off houses recieve AC power which cycles between positive and negative at 60hz ~120v rms in north america. they achieve a potential difference in voltage by basically taking a phase of power, splitting it into two lines and then lagging one line by 90° usually with the use of capacitance from what i was taught back in the day(Good ol ELI the ICEman). this phase shift now gives you a potential difference between those two lines of 240v and 120v between phase and ground. need to use phasor algebra with AC power. when dealing with 3 phase power you still wouldnt just add 120v plus 120v when going phase to phase, you would multiply 120v by the square root of 3 which gives you 208v.
