Why is Complex number notation the way it is?

I was schooled as a Physicists dammit!!
The imaginary number is i!!!
Electric current ALWAYS flows from Positive TO Negative.
charge carrier may flow from negative to positive, such as e- and
Cl- but Na+ flows from positive to negative. If you don't believe
that Na+ and Cl- can flow, try taking a bath in salt water and throw
in a toaster.
IE=P is ALWAYS true, even with AC and a phase factor
Because instantaneous current times instantaneous voltage is equal
to instantaneous power! (in physics everything is instantaneous)
