When a 24.0-W resistor is connected across a 12.0-V battery,a current of 482 mA flows.What is the resulting terminal voltage of the battery?
A)0.4 V
B)5.8 V
C)11.6 V
D)12.0 V

The terminal voltage is calculated using Ohm's Law (V = IR). The current is 482 mA (or 0.482 A), and the resistance is 24.0 ohms. V = 0.482 A * 24.0 ohms = 11.568 V, which rounds to 11.6 V.
