Dissipation factor (D): The dissipation factor of a capacitor is a measure of the energy lost as heat during the operation of the capacitor. It is the ratio of the energy dissipated in the capacitor to the energy stored in it per cycle. A lower dissipation factor indicates that the capacitor is more efficient, as less energy is lost as heat.

  • For electrolytic capacitors, the dissipation factor is around 0.2, and for capacitors with a plastic film dielectric, it is very low, less than 0.01. This indicates that capacitors with a plastic film dielectric generally exhibit lower energy loss compared to electrolytic capacitors.

Here, option 1 is correct.
