Which physical property opposes a change in current flow?

Inductance is the physical property that opposes a change in current flow. This phenomenon occurs due to the creation of a magnetic field around a conductor when current flows through it. When there's a sudden change in current—either an increase or a decrease—the magnetic field responds, generating a voltage that acts in opposition to the change according to Lenz's law. This means that inductance resists changes in the current level and helps to stabilize it over time.

In contrast, capacitance stores electrical energy in an electric field and releases it as the voltage changes, but it does not directly oppose changes in current flow. Voltage is the measure of electric potential difference, and while resistance does impede current, it does not specifically counteract changes in the current itself. Thus, inductance uniquely provides this opposing force to variations in current, making it the correct answer to the question.
