A lamp has 110 volts and 0.9 amperes. What is the resistance?

Explanation:
Using Ohm's law, resistance is found by dividing voltage by current: R = V / I. For this lamp, R = 110 V ÷ 0.9 A = 122.2 ohms. So the resistance is about 122 ohms. The other numbers come from decimal placement or mixing up voltage and current, so they don’t match the actual V/I ratio.
