Which component opposes the change in voltage?

Explanation:
Capacitance resists rapid changes in voltage because it stores charge on its plates. The current through a capacitor is driven by how fast the voltage changes (i = C dv/dt), so a quick voltage change would require a large current to adjust the stored charge. An inductor, on the other hand, resists changes in current, not voltage. Relative motion and frequency aren’t circuit elements. So the capacitor is the component that opposes changes in voltage.
