🔍 Key Concepts

• Voltage regulation in power supplies usually deals with how much the output voltage changes as the load changes • Think about what happens to the output voltage when a power supply goes from no load (nothing connected) to full load (maximum rated current drawn) • Be clear on the difference between input vs. output voltage ratios and load-related changes in output voltage

💭 Think About

• Which choice talks specifically about how the output voltage changes between no load and full load conditions? • Which options are simply describing a basic ratio of input to output, without mentioning any change in load? • If a specification says a supply has "5% voltage regulation," what two operating conditions are being compared to get that percentage?

✅ Before You Answer

• Identify which option explicitly mentions no load and full load conditions • Eliminate choices that only compare input vs. output voltage without mentioning load change • Ask yourself: voltage regulation is usually given as a percentage change in output between two load conditions— which option matches that idea?
