Answer:
9 hours
Explanation:
For each battery:
Current = 1 A
Voltage = 1.5 V
current and EMF required = 5.0 A and 4.5 V
Since each battery has a current of 1 A, we'll need to link five of them in parallel with our load to get a current of 5 A. so that the total current equals 5 amps
. Now that each battery has a 1.5 V voltage drop and we require an emf of 4.5 V, we would use three batteries in series rather than a single battery. So, there is a need to must substitute every single battery with three batteries in series for all five single batteries linked in parallel.
So, the total no. of batteries is
= 5 × 3 = 15 batteries.
On each battery, the charge is = 3 amp hours
∴
The total charge = 15 × 3 = 45 amp hours.
Since the charge transferred within 1 hour = 5 amp
Then, the required lifetime of the battery is:
= 45 amp-hours/ 5 amp
= 9 hours
