What is the current in a circuit with an applied voltage of 120 volts and a resistance of 80 ohms?

To solve this problem, you need to use the Ohm's Law formula for current, which is I = E / R. In this formula, I represents current in amperes, E is voltage in volts, and R is resistance in ohms. Plugging in the numbers provided in the question gives us I = 120 volts / 80 ohms. When you divide 120 by 80, the result is exactly 1.5 amperes. If you accidentally divide the resistance by the voltage (80 / 120), you will land on the distractor 0.667 amperes. If you multiply the two numbers, you will incorrectly arrive at 9600.
