Answer :
Final answer:
The voltage of the lantern battery can be found using Ohm's law, V = I*R. For a current of 0.25 A and a resistance of 48 ohms, the voltage comes to 12 V. Hence, Option 2: 12 V is correct.
Explanation:
The subject of this question is voltage, which is a topic within physics. To solve for voltage, we use Ohm's law, which states that voltage is equal to the current times the resistance (V = I*R). In your case, you have a current (I) of 0.25 amps and a resistance (R) of 48 ohms.
Substitute these values into the equation to find the voltage (V). Therefore the calculation would be V = 0.25 * 48 = 12 V . Therefore, Option 2: 12 V is correct. This provides the voltage of the lantern battery, given the current and resistance.
