D) current and cross-sectional area
E) current and potential difference

Question

Quizplus · Accepted Answer

According to Ohm's law, the current flowing through an ohmic resistor is directly proportional to the potential difference across it. This proportionality constant is the resistance of the resistor, which means resistance is the proportionality constant for current and potential difference.

For an Ohmic Resistor, Resistance Is the Proportionality Constant For
