E) current and potential difference

Question

Quizplus · Accepted Answer

For an ohmic resistor, the resistance (R) is defined by Ohm's Law as the ratio of the potential difference (V) across the resistor to the current (I) flowing through it, which is expressed as R = V/I. This makes resistance the proportionality constant between current and potential difference.
