Which letter in electrical terminology represents current?

In electrical terminology, the letter that represents current is "I." This designation stems from the French term "intensité de courant," which translates to "current intensity." The use of "I" to symbolize current is a standard practice in electrical engineering and circuit analysis, making it essential for understanding electrical formulas and concepts.

The other choices correspond to different electrical quantities: "C" does not have a standard affiliation with an electrical parameter, "V" represents voltage, and "E" often stands for electromotive force (EMF). Each of these terms serves its specific role in the study of electricity, but only "I" is universally recognized as the symbol for current. Understanding these symbols is crucial for anyone in the field, as they are used in Ohm's Law and various circuit equations to analyze and design electrical systems.
