Ohm's Law states resistance can be calculated as the ratio of voltage to current. Which option matches this definition?

Explanation:
Ohm's Law shows how voltage, current, and resistance relate through V = I × R. To isolate resistance, divide both sides by current, giving R = V / I. So “voltage divided by current” directly expresses resistance. For example, with V = 12 volts and I = 3 amperes, R = 12 / 3 = 4 ohms. The other forms don’t give resistance: I / V is the reciprocal of resistance (conductance), not resistance itself; V × I equals power (P = VI); and R / V is not a standard way to express resistance.
