How is electric current related to the rate of flow of charge?

The relationship between electric current (I), charge flow (Q), and time (t) is described by the following formula:

I = Q / t

where:

I = Electric current (measured in amperes, A)

Q = Charge flow (measured in coulombs, C)

t = Time (measured in seconds, s)

In simpler terms, the electric current (I) is equal to the total amount of charge (Q) passing through a conductor divided by the time (t) it takes for that charge to flow through the conductor.

For example, if 10 coulombs of charge pass through a wire in 5 seconds, the electric current in the wire would be:

I = 10 C / 5 s = 2 A

This means the electric current in the wire is 2 amperes, indicating a flow of 2 coulombs of charge per second. Thus, the rate at which charge flows through a conductor determines the magnitude of the electric current passing through it.
