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.
What else can I help you with?
Why inductance is represented by the letter L in electronics?
Because the symbol I was already in common use to represent the amount of current in a circuit.You may ask then why was the symbol I chosen to represent current? Well because the symbol C had already been adopted to represent Capacitance!Go figure!
What is the difference between elecrical and electronics?
in electronics we use DC current but in elctrical equipment we use AC current
Who is the current US CEO of Toshiba Electronics?
The current U.S. CEO of Toshiba Electronics is Hideya Yamaguchi, he is also currently the President of Toshiba Electronics in North America. He is a more recent CEO having taking up the title in June of 2012.
What electronics are diodes used in?
in order to let the current pass in one direction.
What is the definition of electronics engineering?
electronics engineering is the branch of engineering which deals with the flow of current in a semiconductor devices/components. Semiconductor devices/components are those element which made from semiconductors like silicon germanium GaAs and other material. they are widely using in current generation.

How is letter z represented in binary number?
The capital letter Z is represented as: 01011010 Whereas the lower case z is represented as: 01111010
Why we use j in the impedance of a capacitor Why not any other alphabet?
In ordinary mathematics complex number notation uses the letter i for the square root of -1 to identify the imaginary part of the number.But in electronics the letter i was already in use for the AC current in the circuit, so the letter j was used for the square root of -1 instead of the letter i to prevent confusion. So in electronics complex number notation uses the letter j.
What is it called an unknown number represented by a letter or symbol?
An unknown number represented by a letter or symbol is a variable.
What is an regulator?
In electronics it simply means a way to control either voltage and/or current there are mechanical regulators not related to electronics
