If a current of 3 amperes flows, how much charge passes each second?

Explanation:
Current is the rate at which electric charge flows. By definition, 1 ampere equals 1 coulomb per second. So a current of 3 amperes means 3 coulombs of charge pass a point every second. In one second, Q = I × t = 3 A × 1 s = 3 C, which is three coulombs per second. The other options would imply much larger or much smaller currents (hundreds or thousands of coulombs per second, or a few microcoulombs per second).
