really silly nit: why 3+5j instead of 3+5i?

Just scanned through one of my E&M books. Can't find "i" used for
current. Found "I", and dQ/dt. Also found J used for volumn current
density. Lower case "i" is used for imaginary numbers and i^ (that's
i-with-caret) for unit vector along the x axis.
Can't ever recall using "i" for current.
