Problem

Which of the following relations correctly gives the potential difference VV across a conductor in terms of the current II through it and its resistance RR? a) V=2IRV = 2IR b) V=1000 IRV = 1000\,IR c) V=IRV = IR d) V=0.001 IRV = 0.001\,IR
Intuitive explanation

Ohm's Law is the fundamental relationship between voltage, current, and resistance in a conductor. The key insight is that potential difference (voltage) is what drives current through a resistor—the greater the resistance, the more voltage is needed to push the same current through. You're looking for the equation that directly connects these three quantities in their standard form.
