Well, in AC circuits, having √3̅+√-̅1̅ A of current makes as much sense as having 2 amps with a 60° phase shift. It’s just easier notation for calculations - Cartesian coordinates for what would otherwise be polar.

That’s BS notation. If you want Cartesian, just use 3i+1j, no need for some impossible √-1 that you then redefine some operations for, just so it becomes orthogonal to R.

  The nice thing about 𝑖 = √-̅1̅ is that you don’t need to redefine any operations for it, ℐ𝓂 is “automatically” orthogonal to ℛℯ.
