When complex numbers are used to represent AC quantities, the imaginary unit is often denoted as “j” instead of “i” to avoid confusion. This is because some authors use “i” for alternating current and “I” for direct current.

Ah, but who said that the formula was describing electrical currents? The letters i,q,t can stand for other quantities than current, charge, and time. Don’t be so elitist. :-P

Objection! The dimension of the left-hand side is I¹ and the dimension of the right-hand side is I¹T². This means the left-hand side is in amperes and the right-hand side is in coulombs times second, assuming standard SI units. The formula is incorrect and I’m clearly not missing the point of this adorable image.
It’s like pure instinct, but instead it’s “pure autism”.
That makes me Mastered Ultra Autism.
And since I just walked in, now it’s ultra Autism.
Yaaaay, I ed right, even if I couldn’t why.
Meh. Conventions. Like rho vs. r for spherical coordinates. So inconsistent and hard to keep straight.

Not exactly. Current is represented by “I”; current density is represented by “J”.
@Cirrus Light
If I correctly what my grandfather told me (electrical engineer), it’s j when it’s used to describe current anyway.
Yes, but she’s MY dork. :-)
Edited
To be fair, if it weren’t for the q and t, I would’ve thought about the imaginary unit first.
Square root of negative one, that’s exactly what I thought when I saw it.
“i” makes me think imaginary number, not electrical current :q
