What is electrical symbol is used to represent current?
The electrical symbol for a continuous or r.m.s. currentis an italic, upper-case, letter I. The symbol for an instantaneous value of current is an italic, lower-case, letter i.The symbol for its SI unit of measurement, the ampere, is an upright, upper-case, letter A.
What does the letter l represent in electrical terms?
The letter L (written in uppercase) is used as a symbol for inductance. If you mean the letter I (uppercase i), that refers to current.
What is the symbol to represent a joule?
The symbol that is used to represent a joule is the letter "J". This is a derived unit of energy. It can also be used to represent work, and an amount of heat.
Why is the symbol of current is you instead of C?
The symbol for electric current is "I" because it stands for intensity, which is an older term used for electric current. The letter "C" is typically used to represent charge in electrical equations, so using "I" for current helps differentiate between the two.
What letter is used to represents current?
"I" is the letter typically used to represent current in electrical equations.

Why is current represented by the letter I in electronics?
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.
