Understanding the Concepts

* Current (I): The rate of flow of electric charge. Measured in amperes (A).

* Charge (Q): The amount of electrical energy carried by a particle. Measured in coulombs (C).

* Time (t): The duration over which the charge flows. Measured in seconds (s).

The Formula

Current (I) = Charge (Q) / Time (t)

Calculation

* Q = 225 coulombs

* t = 5 seconds

I = 225 C / 5 s = 45 A

Answer: The current is 45 amperes.
