Coulomb measures what?

Explanation:
A coulomb is the unit used to quantify electrical charge. It describes how much charge is present, not how fast it moves or the pressure pushing it. Current is the rate of charge flow and is measured in amperes (coulombs per second). Voltage is the electric potential difference that drives the flow, measured in volts, and resistance is the opposition to current, measured in ohms and related to current and voltage via Ohm’s law.
