Using Ohm's Law, what is the resistance when the voltage is 36 V and the current is 4 A?

Explanation:
Resistance is found by dividing the voltage by the current (R = V / I). With 36 volts and 4 amperes, R = 36 / 4 = 9 ohms. The units V per A simplify to ohms, so the result is 9 Ω. If you check the other options, they would imply different currents for the same voltage: 12 Ω would yield 3 A, 8 Ω would yield 4.5 A, and 10 Ω would yield 3.6 A.
