Current can be expressed in terms of coulombs (C), which measure what quantity?

Explanation:
Coulombs quantify electric charge. Current is the rate at which that charge flows, measured in amperes, which is coulombs per second. So expressing current in terms of coulombs means looking at how much charge passes per unit time. Thus, coulombs measure charge. Voltage is measured in volts and resistance in ohms, so they’re not the quantities described by coulombs. For example, if 3 coulombs pass a point each second, the current is 3 coulombs per second = 3 amperes.
