One explanation I was given was that when a letter was needed to represent current in formulas, C had already been used, and it was decided to use the next unused letter of the alphabet, which was I. However, I prefer the other explanation, which is that in the early days of investigations into electricity, what we now call current was called Intensity, hence the letter I. It should never be confused with Impedence, the symbol for which is Z.

According to my professor at Missouri S&T, Dr. Bijaya Shrestha, current is represented by the letter I in electronics because in the past, scientists used the phrase "Intensity of current" or just "Intensity" to describe current.Similarly, Q is used to represent electric charge because scientists in the past described it using the phrase "Quantity of charge."

Just like any other quantity in algebraic expressions, equations, and formulas,electric current can be represented by any letter or symbol with which you'recomfortable.Out of tradition and force of habit, electric current is most often representedby "I" or "i". But there's no great reason why it has to be.

The expression for impedance is Z=R+jX(Which is in complex form) ; In mathematics complex numbers are represented by real and imaginary components as Z=X+iY(As X,Y,Z are consecutive letters). Hence the impedance is represented by Z.
