One ampere is equal to how many coulombs per second?

Explanation:
Current is the rate at which electric charge flows past a point in a circuit, measured in coulombs per second. By definition, the ampere is that rate: one coulomb flowing every second equals one ampere. So one ampere is equal to one coulomb per second. If more charge passes each second, the current increases—two coulombs per second would be twice the current, ten coulombs per second would be ten times as much, and so on.
