The total active power supplied by a battery source is given by:
P = V × I
Where, P = Active power
V = Voltage
I = Current
Calculation:
Total power supplied by battery = 15 + 10 + 20 = 45 W
45 = V × I
45 = 9 × I
I = 5A
- There is no voltage rating so we can not apply the 'power in series' formula.
- Also, this question is from the official paper of NHPC JE Electrical 5 April 2022 (Shift 1) Official Paper and the official answer is 5, In this question, the discrepancy is found.
