← ScienceWhich mechanism causes current flow within a capacitor during AC voltage changes?
A)Displacement current propagation✓
B)Quantum tunneling effect
C)Electron drift velocity increase
D)Dielectric breakdown cascade
💡 Explanation
A changing electric field between capacitor plates induces a displacement current because Maxwell's equations demand continuity of current flow. Therefore, it is displacement current, rather than quantum tunneling, that contributes to charge separation processes.
