The correct option is Load Regulation

Concept:

Load Regulation:

  • Load regulation refers to the ability of a power supply to maintain a constant output voltage or current despite changes in the load connected to it.
  • In other words, it is the measure of how well a power supply can maintain its specified output voltage or current within a certain tolerance range as the load changes.
  • Load regulation is an important characteristic of a power supply, as it determines the stability and reliability of the power supply's performance in various operating conditions.
  • A power supply with good load regulation will provide a stable output voltage or current, regardless of changes in the load, while a power supply with poor load regulation may exhibit variations in output voltage or current with changes in the load, which can affect the performance of the connected devices or systems.
