    My memory is shit, it was apparently 27 years ago if you’re right but I have no recollection to when it was. But it’s like cycling: it’s simple and once learned you never forget it.

    Now I’m learning how to weld. We’re learning Ohm’s law, which is the same as order of calculation: easy basic shit, a bit far in my memory but you never forget it. But others in my class are really struggling with it. I don’t get it.

    U = I R so R = U / I and I = U / R. P = U I so U = P / I and I = U / P. U=Volt, I=Ampère, R=Ω(Ohm), P=Watt

    This was first year in high school if I remember correctly.
