A device draws 1.1 A at 110 V. What is its resistance?

Explanation:
Ohm’s law ties together voltage, current, and resistance: R = V / I. If a device has 110 volts across it and draws 1.1 amperes, its resistance is 110 divided by 1.1, which equals 100 ohms. The check is consistent: 1.1 A × 100 Ω = 110 V. The other numbers would produce different currents for the same voltage, e.g., 110 Ω would give about 1 A, 90 Ω about 1.22 A, and 120 Ω about 0.92 A.
