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.
 
Yaaaay, I remembered right, even if I couldn’t remember why.

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
@Eroraf86
“i” makes me think imaginary number, not electrical current :q
 
If I remember correctly what my grandfather told me (electrical engineer), it’s j when it’s used to describe current anyway.

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.
