In the SI system of units, one coulomb (1 C) is defined to be the charge that passes a point every second when a constant (electric) current of one ampere, also called one amp, (1 A) flows past that point. Thus, one coulomb equals one ampere second (1 C = 1A s). If Q is the charge and / is the constant (or average) current past a point in a time t, Q=It. An average current of 2.0 A flows through all parts of a wire for 5.0 minutes. How much charge passes by any point in the wire in that time? 10.0 C B. 120.0 C 600.0 C
