Question

batteries are often rated by ampere - hours. this rating is an indication of the potential difference between the electrodes of the battery. the maximum current that the battery can provide to a circuit. the total charge that the battery can provide to a circuit before failing. the total potential energy that the battery can provide to a circuit before failing.

Explanation:

The ampere - hour rating of a battery represents the total charge that the battery can provide to a circuit before failing. It is calculated as the product of the current (in amperes) that the battery can supply and the time (in hours) for which it can supply that current. For example, a 10 - ampere - hour battery can supply a current of 1 ampere for 10 hours or 10 amperes for 1 hour.

Answer:

the total charge that the battery can provide to a circuit before failing.
