Answer :
The power output of the cells is 6 watts and the resistance inside the phone is 6 Ohms.
What is power output?
Power Output can be defined as the average rate of electric energy delivery in a circuit.
The S.I unit of power is Watts (W)
Resistance can be defined as the opposition to the flow of electric current caused by a substance.
The S.I unit of resistance is Ohm, denoted with the symbol (Ω)
How to calculate the power output and resistance
Using the formula given;
Power output, P = VI
where V = voltage = 0.5 × 12 V = 6V
I = current = 1 A
Power output = 6 × 1 = 6 Watts
Resistance = V ÷ I = 6 ÷ 1 = 6 Ohms
Therefore, the power output of the cells is 6 watts and the resistance inside the phone is 6 Ohms.
