Understanding the Concepts
* Voltage (V): The electrical potential difference that drives current. In this case, the batteries are connected in series, so their voltages add up (12V + 12V = 24V).
* Current (I): The flow of electrical charge. Here, it's given as 2.2 amps (A).
* Power (P): The rate at which energy is transferred or consumed. It's measured in watts (W).
The Formula
The relationship between power, voltage, and current is:
* P = V * I
Calculation
1. Voltage (V): 24V
2. Current (I): 2.2A
3. Power (P) = 24V * 2.2A = 52.8W
Answer
The power of the portable radio is 52.8 watts.
