🔍 Key Concepts

• Definition of voltage regulation in a power supply (as a percent) • Relationship between full load voltage and no load voltage • How to convert a percentage into an actual voltage value using the full load voltage

💭 Think About

• Ask yourself: Is the no load voltage higher or lower than the full load voltage when regulation is given as a positive percentage? • How would you express 25% of 200 volts as a number, and how does that relate to the change between full load and no load? • Write a simple equation that starts from the full load voltage and adjusts it by 25% to get the no load voltage.

✅ Before You Answer

• Confirm that voltage regulation (%) is based on the difference between no load and full load voltages, divided by one of them (check your definition). • Be sure you apply the 25% to the correct reference voltage (don’t mix up which voltage is in the denominator). • After calculating, check that your no load voltage is consistent with typical behavior: it should not be lower than the full load voltage for positive regulation.
