You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the resistance?. Select one of the options below as your answer:. . A.. 12 ohms. B.. 0.75 ohms. C.. 3.0 ohms. D.. 0.5 ohms. E.. 6.0 ohms.
Ohm's law states that, V = I x R where V, I, and R are voltage, current, and resistance, respectively. Rearranging the equation gives, R = V / I Replacing the variables with the given values, R = 1.5 volts / 2.0 amp The answer is letter B. 0.75 ohms.
