Using Ohms law, a circuit of 120 volts and a resistance of 15 ohms will have a current of ________ amps.

5 amps would require a resistance of 24 ohms (120/24 = 5), not the 15 ohms specified in the problem.

Ohm's Law defines the relationship V = I x R, which rearranges to I = V/R. Dividing 120 volts by 15 ohms yields exactly 8 amps. This is a direct and unambiguous application of the fundamental Ohm's Law formula when voltage and resistance are both known.

10 amps would require a resistance of 12 ohms (120/12 = 10), not 15 ohms.

12 amps would require a resistance of 10 ohms (120/10 = 12), not 15 ohms.

15 amps would require a resistance of 8 ohms (120/8 = 15), and this choice likely serves as a distractor by matching the resistance value numerically to a current answer.
