What is the resistance of a circuit for which the applied voltage is 12 volts and the current flow is 1.5 amperes?

This is a practical application of Ohm's Law where you are solving for Resistance (R). The formula is R = E / I, where E represents voltage and I represents current. Plugging in the given values, we divide 12 volts by 1.5 amperes. The math works out to 12 / 1.5 = 8, meaning the resistance is 8 ohms. If you incorrectly multiplied the two numbers (12 x 1.5), you would get 18, which is the power in watts and a provided distractor. Dividing them backwards (1.5 / 12) yields 0.125, another incorrect distractor.
