An electric current is the rate at which what quantity flows?

Explanation:
Electric current is the rate at which charge moves through a point in a circuit over time. It tells you how much electric charge passes per second, which is why the unit is the ampere (1 ampere = 1 coulomb per second). The other ideas don’t describe charge movement: mass flow relates to fluids, force is a push or pull, and energy measures the capacity to do work (with power being energy per time, not charge flow).
