How does high resistance in filter chokes affect power supply performance?

• A. Improves voltage output
• B. Stabilizes performance
• C. Contributes to poor regulation
• D. Has no effect

Answer: (C)

High resistance in filter chokes can significantly impact power supply performance by contributing to poor regulation. When filter chokes have high resistance, they limit the amount of current that can flow through them. This results in an increased voltage drop across the choke, leading to a situation where the voltage output of the power supply is less stable and can experience wider fluctuations based on load conditions. As the load increases, the higher resistance in the choke can lead to inadequate current supply, causing the output voltage to sag and making it difficult for the power supply to maintain a consistent output. Thus, this situation can negatively influence the overall performance of the power supply, especially in applications where stable and precise voltage is critical.
