Concept:

A capacitor is an electrical component that stores and releases electrical energy in a circuit. It is commonly used in applications that require power conditioning, signal processing, and energy storage. Capacitors are crucial in devices where quick charge and discharge cycles are required.

Among the given options:

  • Transformer: Uses inductors primarily, not capacitors.
  • Microwave: Uses capacitors, but not as the primary component for energy storage.
  • Electric Vehicle: Heavily relies on capacitors for energy storage, regenerative braking, and power conditioning, making it the primary application for capacitors among the listed options.
  • Toaster: Uses resistive heating elements and does not significantly involve capacitors.
