The correct answer is: 48 ampere-hour capacity would deliver a current of 8 amperes for 6 hours.
An ampere-hour (Ah) is a unit of electric charge equal to one ampere flowing for one hour. It is a measure of the capacity of a battery to store electrical energy. The higher the Ah rating of a battery, the longer it can provide a given amount of current.
In this case, a 48 Ah battery can deliver a current of 48 amperes for one hour, or 24 amperes for two hours, or 12 amperes for four hours, and so on. However, the longer the battery is discharged, the lower the current it will be able to provide. For example, if the battery is discharged for six hours, it will only be able to provide a current of 8 amperes.
The other options are incorrect because they do not take into account the fact that the current a battery can provide will decrease as the battery is discharged.
