How resisrer inducter and capaciter work in ac and dc power supplys?

In a DC power supply, resistors limit current, while inductors and capacitors primarily act as energy storage devices; capacitors charge and discharge, smoothing voltage fluctuations, while inductors resist changes in current. In AC power supplies, resistors still limit current, but inductors and capacitors interact with the alternating current: inductors store energy in magnetic fields and oppose changes in current, while capacitors store energy in electric fields and phase-shift the voltage. This behavior in AC circuits leads to concepts like impedance and resonance, which are crucial for applications like filters and oscillators. Overall, each component plays a distinct role in managing voltage and current in both types of power supply systems.
