Hint: Nowadays, the capacitor is employed in different-different electronics devices. Electronics devices are wont to work on the AC current and sometimes on the DC current. It stores charge during the time of the DC circuit and it also changes the polarity during the time of the AC circuit.

Complete step by step solution:
A capacitor is formed from metallic plates with a dielectric material in between the plates. Once you apply a voltage over the 2 plates, an electrical field is created, and a capacitor works by storing energy electrostatically in an electrical field. A capacitor is an electronic component that stores and releases electricity during a circuit. It also passes AC without passing a direct current. A capacitor is an important part of a digital device and is thus almost invariably used in a digital circuit.

Yes, a capacitor itself doesn't convert an AC to DC. However, capacitors are linked across bridge rectifiers to get a smoother ripple-free DC signal. It means pure DC, as from a battery or a well-filtered AC-to-DC power supply. Ripple refers back to the remnants of AC that squeak via poorer-excellent supplies.

Hence, a capacitor itself doesn't convert an AC to DC.

Additional information:
Use of capacitors:
- Suppression and coupling
- Power factor correction
- Pulsed power and weapon
- Energy storage

Note: Capacitors are extensively utilized in our machinery and additionally damage it. Capacitors are major reasons for failure in digital systems. Capacitors fail for varied reasons, like wear out, aging, opposite polarity voltage causing harm, mechanical harm during assembly, dielectric failure, excessive temperature causing harm during soldering, operation, testing, etc.
