Capacitor vs Inductor – Do You Know the Difference? Both capacitors and inductors store energy, but they do it in completely different ways! Capacitor: Stores energy in an electric field Opposes changes in voltage Acts as an open circuit in steady-state DC Inductor: Stores energy in a magnetic field Opposes changes in current Acts as a short circuit in steady-state DC Quick Memory Trick: Capacitor = Voltage-focused device Inductor = Current-focused device These two components are the foundation of power supplies, filters, motor drives, converters, PLC systems, automation panels, and countless electronic circuits. Which component is more commonly used in VFDs and power electronics: Capacitor or Inductor? Comment your answer below! Post navigation LOAD CELL WORKING – SIMPLE EXPLANATION
