If a device has voltage 24 V and current 3 A, what is its resistance?

Explanation:
Ohm’s law. Resistance equals voltage divided by current, so R = V/I. With 24 V and 3 A, R = 24/3 = 8 ohms. The other numbers would require different currents for the same voltage (12 Ω would need 2 A, 6 Ω would need 4 A, 24 Ω would need 1 A), so only 8 Ω matches the given values.
