What is the output of power in watts for a 3V battery driving a 15 Ohm resistor?

To determine the output power in watts for a 3V battery driving a 15 Ohm resistor, we can use the formula that relates power (P), voltage (V), and resistance (R):

[ P = \frac{V^2}{R} ]

In this case, the voltage ( V ) is 3 volts, and the resistance ( R ) is 15 ohms. Substituting these values into the equation gives:

[ P = \frac{3^2}{15} ] [ P = \frac{9}{15} ] [ P = 0.6 \text{ W} ]

Therefore, the correct calculation shows that the output power is 0.6 watts, which is not shown among the given choices, suggesting that C. 0.5 W may be the closest approximation or a typo in typing out the correct numerical results in the options.

To clarify further, 0.5 watts would be a possible option if approximating, but based on strict calculation from the values given, it's essential to recognize that the more accurate computed power is indeed 0.6 watts.

If the options presented include direct calculated outputs, and C was denoting correctness with
