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

Explanation:
To determine the resistance of a circuit when the voltage and current are known, Ohm's Law can be applied. Ohm's Law states that Voltage (V) = Current (I) × Resistance (R). To find resistance, the formula can be rearranged as R = V / I. Here, the applied voltage is 12 volts and the current flow is 1.5 amperes. Plugging these values into the rearranged formula gives: R = 12V / 1.5A = 8 ohms. Hence, the resistance of the circuit is 8 ohms, which corresponds to the choice stated. This calculation demonstrates the direct relationship between voltage, current, and resistance in an electrical circuit as outlined by Ohm’s Law.
