Given details:
Capacity of the battery is 12mAh
Discharge is at C/4 rate
Solution:
We know that,
- For a 1Ah battery rated at 1C, discharge will be 1A current for one hour.
- For a 12mAh battery rated at 1C, discharge will be 12mA current for one hour.
Similarly, C/2 rate means two hour discharge.
In our scenario, for a C/4 rate of discharge of 12 mAh battery, 3 mAh current is discharged in four hours.
Answer:
The time taken for complete discharge will be 4 hours.
Hope it helps.
