Give the equation for Ohm's Law.

Explanation:
Ohm’s Law shows how voltage, current, and resistance relate: voltage equals current times resistance (E = I × R). To express resistance in terms of voltage and current, rearrange this equation to R = E / I. Since E represents voltage in the problem, R = E / I is the form that matches Ohm’s Law for solving for resistance. The other forms would not reflect how current scales with voltage and resistance: they would misrepresent the relationship by multiplying rather than dividing, or by swapping the roles of the variables.
