The coulomb is the SI unit of which electrical quantity?

Explanation:
The key idea here is understanding which electrical quantity a coulomb measures. The coulomb quantifies the amount of electric charge. In circuits, current is the rate at which charge flows and is measured in amperes, where 1 ampere equals 1 coulomb per second. Resistance is measured in ohms, and electric potential (voltage) is measured in volts (joules per coulomb). So the coulomb is specifically the unit for electric charge, not for the flow rate, resistance, or potential.
