A flow of one coulomb per second past a point in a circuit describes which quantity?

Explanation:
Electric current is the rate at which charge moves past a point in a circuit. If charge flows at one coulomb every second, the current is one ampere. An ampere is defined as 1 C/s. This is different from voltage (potential difference), measured in volts; resistance, measured in ohms; and power, measured in watts. So the described flow corresponds to electric current, measured in amperes.
