Understanding the Concepts

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

* Charge (Q): The amount of electricity. Measured in Coulombs (C).

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

The Relationship

These quantities are related by the following equation:

* Q = I * t

Solving the Problem

1. We know:

* Q = 9 Coulombs

* I = 3 Amperes

2. We need to find:

* t (time)

3. Rearrange the equation to solve for time (t):

* t = Q / I

4. Substitute the values:

* t = 9 C / 3 A

5. Calculate:

* t = 3 seconds

Answer: It takes 3 seconds for 9 coulombs to pass a current of 3 amps.
