A 16 Ah (Ampere-hour) battery will provide a current of 2 A for...

  • A

    32 hours

  • B

    8 hours

  • C

    16 hours

  • D

    4 hours

Ampere-hours describe battery capacity in units that are convenient for calculations. The battery capacity is calculated as:

Capacity (Ah) = Current (A) x time (hours)

If we want to know how long a battery of a given capacity will last for a certain amount of current, we can re-arrange the equation;

time (hours) = Capacity (Ah) / Current (A)

For this question;

time = 16/2 = 8 hours
