The topic of this problem is Electric Current and Charge.

The problem is to determine how much time is required for

a 12 amp charger to deliver 3600 coulombs of charge to a battery.

This problem uses the basic equation for current.

That is the current is equal to the change in the charge divided by

the change in time.

So it's per unit time.

In that case, we're looking for the amount of time is required to for

this 12 amp charge to deliver 3600 coulombs of charge.

So we need to rearrange the equation and solve for the amount of time.

So it's equal to the change in the charge over the current.

And so in this case, we have 3600 coulombs of charge and

we have a 12 amp maximum charger.

And so that gives us 300 seconds.

It will take 300 seconds for this charger

to charge 3600 coulombs of charge to a battery.
