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)
