Final answer:
The current flowing is 5 amperes.
Step-by-step explanation:
The current in a circuit is determined by the rate of flow of charge. An ampere is the flow of one coulomb of charge through an area in one second. In this case, 15 coulombs of charge flow every 3 seconds, so the current can be calculated by dividing the charge by the time:
Current = Charge / Time
Substituting the given values:
Current = 15 C / 3 s = 5 A
Therefore, the current flowing is 5 amperes.
