What is the unit used to measure electric charge?

Explanation:
Charge is quantified in coulombs. One coulomb equals the amount of charge moved when a current of one ampere flows for one second. This links current and time: current tells you how fast charge moves, while coulombs tell you how much charge there is in total. The other units describe different things—ampere is the rate of charge flow (current), volt is energy per unit charge (potential difference), and ohm is resistance. For context, the electron carries about 1.6 × 10^-19 coulombs, so many electrons add up to a measurable coulomb.
