C Correct answer
Explanation

Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the constant of proportionality being the resistance (R). The correct formula is R = V/I, which can be rearranged to V = IR. Option A has the division reversed, option B multiplies V and I incorrectly, and option D has V squared which is incorrect.
