If current equals 2 amperes and resistance equals 4 ohms, what is the voltage difference?

Explanation:
Voltage follows Ohm’s law: V = I × R. With a current of 2 amperes and a resistance of 4 ohms, the voltage difference is 2 × 4 = 8 volts. The units align because ampere times ohm gives volt. The other numbers would require different current or resistance values, so they don’t match the given conditions.
