  When talking about AC power, some of the power consumed doesn’t actually produce real work. It gets used in the generation of magnetic fields and charges in inductors and capacitors.

  The power being used in an AC system can be simplified by using a right triangle. The x axis is the real power being used by resistive parts of the circuit (in kilowatts, KW). The y axis is reactive power, that is power being used to maintain magnetic fields and charges (in kilovolt-amperes reactive, KVAR). And the hypotenuse is the total power used by the circuit, or KVA (kilovolt-amperes).

  Literal side note: they’re all the same units, but the different sides of the triangle are named differently to differentiate in writing or conversation which side of the power triangle is being talked about. Also, AC generator ratings are given in KVA, so you need to know the total impedance of your loads you want to power and do a bit of trig to see if your generator can support your loads.

  The reactive component of AC power is denoted by complex numbers when converting from polar coordinates to Cartesian.

  Anyways, I almost deleted this because I figured your comment was a joke, but complex numbers and right triangles have real world applications. But power triangles are really just simplifications of circles. By that I mean phasors rotating in a complex plane, because AC power is a sine wave.

  That was a large part of the charm for me in Tunic. The core mechanic was collecting pages of the instruction booklet as you adventured so you could learn the mechanics of the game. The other part of that being the manual was written in an unknown language* and you’d need to infer what the instructions meant using context clues. It was an absolute blast and hit the dopamine button when I figured out some puzzles.

  I know the asterisk is not entirely correct
