C = Average. This is the basic level that all professors expect of college students. When students turn in C-level work, they have answered all questions at the minimum level expected for competency in the course, but they have not pressed beyond that point.

Who invented AC current?

While early concepts existed, Nikola Tesla is credited with inventing and developing the practical alternating current (AC) system, including the polyphase induction motor and the entire AC generation/transmission system, making it efficient for widespread use against Thomas Edison's direct current (DC). Tesla's work in the 1880s led to the AC power grid we use today, featuring easily convertible voltages for long-distance transmission.
