What does j mean?

imaginary unit (j or i) is a mathematical concept that is equal to the square root of -1.
It is used in complex numbers and in certain types of mathematical equations.

Note:
Since the symbol "i" is already used to represent the electrical current, the symbol "j" is often used in its place to denote the imaginary component of a complex number in electronic circuit analysis.
