SUMMARY
AC current flows through a capacitor due to the phenomenon known as "displacement current," which allows for the transfer of energy despite the lack of physical continuity between the capacitor's plates. The impedance of a capacitor varies with frequency, contrary to the concept of resistance, which remains constant. Understanding these principles is crucial for grasping the behavior of capacitors in AC circuits.
